The family Cervidae ranks among the most diverse modern taxonomic groups of herbivores, with even greater diversity in the geological past. This ecological flexibility and opportunism align deer closely with hominins. The relationship between cervids and hominins was crucial for hominin survival during glaciation phases and likely played a role in the colonization of the New World by Paleolithic humans. Studies on the taxonomy and systematics of fossil cervids continue to yield new discoveries and insights. Recent research has revealed that the natural history of the genus Cervus in Europe is more complex than previously thought. We suggest that earliest representative of the genus is the small-sized Cervus nestii (Azzaroli, 1947) n. comb. from the Early Pleistocene of Italy, characterized by simple four-pointed antlers lacking a bez tine. The onset of the Middle Pleistocene saw the emergence of the large-sized red deer, with subspecies exhibiting antlers featuring a bez tine but no crown, known as Cervus elaphus acoronatus Beninde, 1937. Subsequently, approximately 400 000 years ago, the “modern” Cervus elaphus Linnaeus, 1758 emerged, displaying high plasticity, diversification, and giving rise to several subspecies during the Late Pleistocene. Our recent revisions at a European scale have uncovered the presence of the wapiti, Cervus canadensis Erxleben, 1777, a species currently inhabiting North America and Asia. From Crimea to Sweden, several subspecies previously attributed to the red deer have been reinterpreted and associated with the wapiti.

RÉSUMÉ Des continents aux îles : suivre le cerf élaphe (Cervus elaphus Linnaeus, 1758) et son « cousin gênant », le wapiti (Cervus canadensis Erxleben, 1777) en Europe. Les cervidés représentent une famille particulière d’herbivores ruminants qui a développé une stratégie écologique et évolutive, flexible et opportuniste. Cela leur a permis de développer de grandes ramures de bois, qui tombent et repoussent chaque année et qui nécessitent donc beaucoup de ressources et d’énergie. La famille des cervidés est l’un des taxons d’herbivores actuels montrant la plus grande diversité, diversité encore plus forte au cours des époques géologiques anciennes. Cette flexibilité écologique et cet opportunisme rapprochent les cervidés des hominines. La relation entre les cervidés et les hominines a été cruciale pour la survie des seconds pendant les phases de glaciation et a probablement joué un rôle dans la colonisation du Nouveau Monde par les groupes humains du Paléo lithique. Les études sur la taxonomie et la systématique des cervidés fossiles continuent d’apporter de nouvelles découvertes et de nouvelles idées. Des recherches récentes ont révélé que l’histoire naturelle du genre Cervus en Europe est plus complexe qu’on ne le pensait. Nous suggérons que le premier représentant du genre est le petit Cervus nestii (Azzaroli, 1947) n. comb. du Pléistocène inférieur d’Italie, caractérisé par des bois simples à quatre pointes dépourvus de sur-andouiller. Le début du Pléistocène moyen a vu l’émergence du cerf de grande taille, avec des sous-espèces présentant des bois munis de sur-andouiller mais sans couronne, connues sous le nom de Cervus elaphus acoronatus Beninde, 1937. Par la suite, il y a environ 400 000 ans, le Cervus elaphus Linnaeus, 1758 « moderne » est apparu, faisant preuve d’une grande plasticité et d’une grande diversification, et donnant naissance à plusieurs sous-espèces au cours du Pléistocène supérieur. Par une révision récente des données à l’échelle européenne nous proposons l’identification du wapiti, Cervus canadensis Erxleben, 1777, une espèce qui habite actuellement l’Amérique du Nord et l’Asie. De la Crimée à la Suède, plusieurs sous-espèces précédemment attribuées au cerf élaphe ont été réinterprétées et associées au wapiti. INTRODUCTION Deer (family Cervidae) are one of the most diverse modern groups of ruminant herbivores, distinguished by their unique cranial appendages. Unlike other ruminants, these appendages, known as antlers, become inert bony structures at the end of their biological cycle. The evolution and characteristics of antlers have fundamentally shaped the evolution, ecology, geographical distribution, relationships with other herbivorous mammals, and interactions with humans. To understand these features and relationships, it is essential to comprehend the biological advantages and constraints that antlers confer. With few exceptions, antlers develop only in males and, depending on the species, may serve multiple functions. Primarily, antlers function as weapons during male-male competition for breeding opportunities, establishing hierarchies among males and playing a crucial role in sexual selection (Goss 1983; Geist 1998). A secondary function derived from this is visual communication, including conveying information about the health status and social standing of the male individual. In highly specialized cases, such as in giant deer with large palmated antlers, visual communication may outweigh the intraspecific fighting function. While antlers exhibit consider able variability, their function as organs of communication remains a crucial factor in preventing interbreeding between species. This is because the visual signals conveyed by antlers are speciesor even subspecies-specific (Geist 1998). Additional functions of antlers include protective roles provided by their ramification, such as fixing rivals’ antlers, defense against predators, and the thermoregulatory function of growing antlers, which are rich in blood vessels and covered by skin (Stonehouse 1968; Goss 1983; Lister 1987a, Geist 1998; Croitor 2020a). Exceptions among cervids include reindeer (Rangifer tarandus (Linnaeus, 1758)), as both males and females possess antlers, and Chinese water deer (Hydropotes inermis Swinhoe, 1870), whose males have lost their antlers (Flerov 1952). The development of antlers in female reindeer represents an adaptation, allowing females to defend the snow pits they dig to access lichens hidden beneath the snow from larger, stronger males (Tarasov 1956). Hence, antler shedding in reindeer males and females occurs asynchronously: males shed their antlers soon after the rutting season, while females shed theirs during springtime (Flerov 1952; Sokolov 1959). In Hydropotes, the function of antlers as an offensive rutting weapon is entirely replaced by very large saber-shaped upper tusks that attain 8 cm in length. Male deer undergo annual cycles of antler growth and shedding, a unique evolutionary trait among mammals that entails significant energetic costs. The developing antlers are covered with vascularized skin, the “velvet”, which covers the cartilaginous growing antler until its ossification, after which the skin is discarded and shed (Goss 1983). This process necessitates access to abundant, high-quality food resources rich in minerals and proteins. Such physiological specialization and dietary requirements serve as the cornerstone of cervid ecological opportunism and adaptability, representing an optimal MOTS CLÉS Cervidae, morphologie, biodiversité pléistocène, biodiversité holocène. 145 ANTHROPOZOOLOGICA • 2025 • 60 (11) From continents to islands: tracking the red deer and its “troublesome cousin”, the wapiti, in Europe strategy for obtaining highly nutritious food. In addition to their preference for highly nutritious plant parts, cervids have also been observed occasionally consuming small vertebrates, bird eggs, and gnawing bones and shed antlers to acquire proteins and minerals (Flerov 1952). This feeding opportunism significantly influences the ecological and evolutionary strategy of the family Cervidae and the principles of ecological resources partitioning within the family (Geist 1998). The family Cervidae is characterized by a wide range of body masses, with the smallest species being the pudu (25 to 45 cm tall at the shoulder, weighing 6 to 15 kg) and the largest being the moose Alces alces (Linnaeus, 1758) (male: 2.30 m tall at the shoulder, weighing 630 kg) (Flerov 1952; Geist 1998). Since the craniodental morphology in cervids, compared to bovids, remains relatively unspecialized, the difference in body mass is likely the primary eco-physiological factor ensuring ecological niche partitioning among sympatric species (Lister 1987a). The paleodiet analysis and frequency of cervid species that come from the same faunas show that body mass does not have a decisive influence upon forage choice, but rather influence the selection of habitats (Kaiser & Croitor 2004). This is the reason why we practically never find in the same fauna modern cervid species with similar body size. The term “fauna” is applied to fossil communities somehow arbitrarily. However, in the same way as in modern faunas, it is rare to find cervid species with similar body sizes and comparable frequencies of remains within the same fossil assemblage (Heintz 1970; Lister 1999; Croitor & Bonifay 2001). Modern roe deer of the genus Capreolus exemplify adaptations to specific ecological niches for small-sized deer in temperate climates with pronounced seasonality. The two extant species, Capreolus capreolus (Linnaeus, 1758) and Capreolus pygargus Pallas, 1771, typically weigh around 35-40 kg and 55-60 kg, respectively (Flerov 1952). Throughout their range, they coexist with larger cervids such as Cervus elaphus Linnaeus, 1758, Cervus canadensis Erxleben, 1777, Cervus nippon Temminck, 1836, Dama dama (Linnaeus, 1758), and Alces alces. The relatively small body size of roe deer is an adaptation to the niche of small-sized ruminants in the mid-latitudes of Eurasia (Geist 1998). This specialization necessitates additional biological adaptations, such as prolonged gestation, to align their reproductive cycle with the seasonal patterns of these regions (Geist 1998). The evolutionary significance of body size reduction in continental Capreolus as an adaptation to resource partitioning among larger cervids is highlighted by the evolution of Capreolus in the conditions of insular isolation. Capreolus miyakoensis Hasegawa, Ōtsuka & Nohara, 1973 from the Late Pleistocene of Miyako Island attained a larger body size comparable to that of modern sika deer (Takakuwa et al. 1999). This increase in size in the insular roe deer from Japan is an unusual evolutionary trend for cervids under insular isolation. Typically, according to the “island rule”, cervid lineages in isolated insular environments, absent terrestrial predators, tend to reduce their body size and develop “paedomorphic” cranial features (Sondaar 1977). However, C. miyakoensis, which did not face direct competition from larger deer, evolved to a body size comparable to fallow and sika deer. The potential influence of carnivores on the evolution of C. miyakoensis’ body size can be dismissed, as the insular fauna included only a single predator, a small-sized cat (Oshiro & Nogara 2000). Although the idea about body size difference as an ecological partitioning adaptation among sympatric cervid species was not explicitly explained, the size difference in teeth and postcranial bones remains reliable and broadly used method of separation of remains of sympatric species or species that come from the same fossil fauna (Zdansky 1925; Heintz 1970; Lister 1999). Cervids exhibit limited ecological competitiveness compared to bovids, the latter being highly specialized for narrower and well-defined ecological niches with sophisticated eco-morphological adaptations facilitating the exploitation of resources and ecological partitioning among herbivore species (Spencer 1995; Geist 1998). The advanced eco-morphological specialization observed in African bovids, and other Afrotropical herbivores serves as the cornerstone guiding the establishment and functioning of the diverse herbivore communities within the stable ecosystems of Africa (Spencer 1995). The limited ecological competitiveness of cervids, particularly in comparison to bovids, explains their inability to establish themselves within the African continent, dominated by diverse herbivore communities largely comprised of bovid species (Geist 1998). The endemic species Megaceroides algericus (Lydekker, 1890) represents an exceptional instance of cervid dispersal into Africa, likely taking place during a glacial phase that destabilized the Afrotropical ecosystems in North Africa. African endemic deer species persisted until the early Holocene, evolving extreme craniodental adaptations within a marginal ecological niche inaccessible to bovids: the periaquatic habitat, providing soft aquatic plants as a mineral-rich food source (Croitor 2016). In the Palearctic region, which has experienced significant climate fluctuations over the past few million years, cervids have had a distinct advantage over bovids. Palearctic bovids predominantly occupy ecological niches characterized by relatively limited resources but maintain stability through various climate changes. These niches include mountainous and alpine ecosystems, as well as desert and semi-desert areas (Sokolov 1959; Crégut-Bonnoure 2007). During the Pleistocene, the evolutionary diversity of bovids in the Palearctic region became relatively restricted compared to the Ethiopian and Oriental zoogeographic areas. This diversity is mainly seen in the subfamily Caprinae, which underwent extensive evolutionary radiation in the mountainous areas of Eurasia, regions that remained largely inaccessible to cervids (Simpson 1945; Sokolov 1959; Geist 1987; Crégut-Bonnoure 2006, 2020). Deer excel as good colonizers of newly available habitats in young emerging ecosystems devoid of competition from other large herbivores, readily switching between food resources provided they offer sufficient nutritional value (Geist 1998). This physiological trait has profoundly influenced cervid morphology, evolution, and biogeography. Consequently, cervids typically exhibit low craniodental specialization, primarily maintaining primitive brachyodont dentition (Flerov 1952). Cervids did not evolve advanced hypsodont teeth due to their feeding habits, which primarily involve nutrient-rich and soft plant parts. This physiological requirement for high-quality, abundant forage 146 ANTHROPOZOOLOGICA • 2025 • 60 (11) Croitor R. & Crégut-Bonnoure É. diminishes the ecological competitiveness of cervids, particularly in the presence of bovid competitors (Geist 1998). Cervids achieved notable success in colonizing North and South America, regions characterized by a very poor diversity of large herbivores during the Pliocene (Geist 1998; Webb 2000). In these regions, they underwent a prolific secondary evolutionary radiation comparable to the diversified early evolutionary radiations in the Old World (Geist 1998; Webb 2000; Croitor 2022). Cervids are among the few large herbivore groups that effectively exploited newly available territories following glacial retreats (Geist 1998; Meiri et al. 2013; Croitor 2022). Additionally, they have demonstrated remarkable adaptability to conditions of insular isolation (Caloi & Palombo 1995). Thus, the highly diverse deer, with their large, branched, and often bizarre antlers, were among the first exotic animals encountered by ancient humans during their out-of-Africa journey. Despite evolving in different biogeographic contexts, deer and humans shared a common trait: ecological opportunism and the ability to colonize new territories and ecosystems. These shared characteristics facilitated a close relationship between human societies and deer. Among the most evolutionarily specialized members of the family Cervidae, the reindeer (Rangifer tarandus) has developed exceptional adaptations to the cold Arctic climate (Flerov 1952; Tarasov 1956). Reindeer played a crucial role in human dispersals into high periglacial latitudes and significantly contributed to the survival of human populations in Europe during glacial phases (Bouchud 1966). It is conceivable that reindeer were an important resource that enabled Paleolithic humans to colonize America. Notably, reindeer remains the only domesticated deer species. Although there have been relatively recent attempts to domesticate the moose (Alces alces) and employ it as draft animals, these efforts have failed due to several constraints imposed by cervid physiological requirements (Sokolov 1959). Firstly, deer require high-quality and nutrient-rich forage, rendering them economically less advantageous than the less demanding domesticated bovids (Bos taurus Linnaeus, 1758, Ovis aries Linnaeus, 1758, Capra hircus Linnaeus, 1758). Secondly, the attempts to utilize moose as draft animals failed because they were not sufficiently hardy and often died from overheating (Sokolov 1959). Nonetheless, deer have remained an important game species throughout prehistoric and historical times. The true Cervidae have been documented since the Early Miocene, with genera such as Procervulus, Dicrocerus, Acteocemas, Euprox, and Amphiprox (Vislobokova 1990). The evolutionary radiation of the modern subfamilies Cervinae and Capreolinae occurred during the Late Miocene in two distinct zoogeographic areas of Eurasia: Southeastern Asia and Europe, respectively (Croitor 2022). The Late Miocene evolutionary radiation of capreolines was as diverse as the radiation of cervines, encompassing taxa which exhibit morphological convergence with some modern Eurasian cervines and extinct South American deer species (Croitor 2021, 2022). However, the taxonomic diversity of European capreolines was significantly reduced by numerous extinctions by the end of the Miocene (Croitor 2021). Today, they are represented by highly evolved species occupying ecological niches that are rather extreme for cervids (Geist 1998). The subfamily Cervinae remains diverse and relatively intact to the present day, encompassing a range of modern species that exhibit varying degrees of evolutionary specialization, from the small-sized tropical Muntiacus and Elaphodus to the very large C. canadensis, which displays advanced adaptations to the comparatively cold Holarctic climate (Geist 1998). The genus Cervus is distributed throughout the entire Palearctic region and includes three modern species: the red deer (C. elaphus) in Western Eurasia and Central Asia, the wapiti (C. canadensis) in Siberia and mountainous regions of East Asia, and the sika deer (Cervus nippon) in Eastern Asia. Recent evidence suggests that the Atlas red deer from North Africa is the result of artificial introduction of European red deer by humans (Doan et al. 2017). The paleontological record of the genus Cervus in Western Eurasia begins after the important Pachycrocuta brevirostris Aymard, 1846 event (sensu Martínez-Navarro 2010) –also known as the “Wolf event” (Azzaroli 1983)– which designates the decline of archaic warm-loving faunas containing many Pliocene holdovers, but also marked the first confirmed presence of hominins in Eurasia (Martínez-Navarro 2010). Despite numerous publications on the evolution, paleoecology, and diversity of Cervus in Europe, gaps remain in our understanding of the natural history of this genus. This paper aims to provide a comprehensive bibliographic overview of the available information on the diversity and evolution of the genus Cervus in Western Eurasia and to highlight areas where further research is needed to fill these gaps in our knowledge about red deer and its relatives in Europe. ORIGIN AND DIVERSITY OF THE GENUS CERVUS Cervus is the most successful modern genus of cervids, boasting an extremely vast distribution across Eurasia and North America. Nevertheless, Cervus retains many primitive features in its cranial morphology. The genus Cervus is characterized by a moderately flexed braincase (less than in Dama), relatively long pedicles that are somewhat divergent and inclined caudally, a narrow triangular basioccipital (similar to Muntiacus and Rusa), small upper canines, and long naso-premaxillary articulation (Heptner & Zalkin 1947; Flerov 1952). The cranial and dental specialized characters are few. The nasal bones are relatively long (longer than the upper tooth row), although they do not reach the line connecting the anterior edges of the orbits. Antlers of representatives of the genus Cervus are covered with a characteristic pearling (Averbouh 2016) or “perlation” (Goss 1983), making them easily distinguishable from most other cervid genera. The knobby appearance of the antler surface arises from the periosteum of growing antlers, which is responsible for the development of the pearling. The pearled antler surface is a specific morphological feature of the genus Cervus and some related forms that are sometimes also included in Cervus, such as Rusa unicolor (Kerr, 1792) and Rusa timorensis Blainville, 1822. Typically, antlers of the genus Cervus have four to five or more tines, including the brow tine (the evolutionarily oldest and most consistent element of Cervus antlers), the bez tine (an additional basal tine 147 ANTHROPOZOOLOGICA • 2025 • 60 (11) From continents to islands: tracking the red deer and its “troublesome cousin”, the wapiti, in Europe seen in larger, more advanced species), the trez tine (or middle tine, corresponding to the anterior tine of the distal fork in Rusa), and distal crown tines, which emerged during the evolutionary transition to fourand five-tined antlers (Fig. 1). The origin of the genus Cervus is linked to a deer form with three-pointed antlers similar to modern Rusa. The first appearance of a true representative of the genus, Cervus magnus (Zdansky, 1925) (= Pseudaxis magnus Zdansky, 1925), is reported from the beginning of the Early Pleistocene in China, dating back to around 2.6 million years ago. Cervus magnus represents the next step in antler evolution by developing an additional tine in the distal part of the antler. Its antlers are characterized by the presence of a single basal tine (brow tine), a trez tine, and a small crown tine situated on the posterior side of the distal part of the main beam, which appears to be a homologue of the first crown tine in modern-type wapitis (Fig. 2A). According to Geist (1998) and Di Stefano & Petronio (2002), C. magnus is the earliest species of the genus Cervus. However, the antlers of C. magnus are already too specialized and represent the evolutionary stage of the evolved parasagittal crown as in modern C. canadensis. We rather consider that C. magnus is probably a direct precursor of C. canadensis and represents the evolutionary stage after the split of red deer and wapiti lineages (Croitor 2020a). The lineage of European red deer is first recorded in the Early Pleistocene of Western Eurasia. Around 2 million years ago, Cervus nestii (Azzaroli, 1947) n. comb. (originally published as Dama nestii Azzaroli, 1947) with four-tined antlers emerges as the oldest European representative of the “elaphus” group (Kahlke 2001; Croitor 2006, 2011, 2018). It is found in Georgia (= Cervus abesalomi Kahlke, 2001; Dmanisi site, 1.8-1.76 million years old) as well as in Italy (Valdarno, Tuscany; probably between 2.0 and 1.3 million years ago; Olivola, approximately 2.1-1.9 million years ago: Croitor 2014). The paleontological record of the earliest Cervus in Western Eurasia has been clouded by decades of taxonomic debate. A key role in understanding the early evolution of the Cervus lineage, which led to the modern red deer, is played by a small-sized deer with simple antlers from the Early Pleistocene of Italy. Azzaroli (1947) identified this cervid from the Upper Valdarno as Dama nestii nestii (Azzaroli, 1947), distinguishing it from Dama nestii eurygonos (Azzaroli, 1947) based on differences in distal antler bifurcation and other antler characteristics. Petronio (1979) later elevated both forms to species rank, citing their distinct morphological traits. In 1992, Azzaroli reclassified Dama nestii Azzaroli, 1947 into the genus Pseudodama, describing Dama eurygonos (Azzaroli, 1947) as an “advanced form” of Dama nestii. The genus Pseudodama is poorly defined, primarily by helicoidal antler beams, and encompasses significant variability in traits such as dental morphology (presence or absence of a cingulum in upper molars, simple or molarized fourth lower premolars), pedicle shape and position (short and vertical vs. long and caudally sloped), braincase shape fig. 1. — Antler shapes of Cervus elaphus Linnaeus, 1758 (A) and Cervus canadensis Erxleben, 1777 (B) with labeled terms for antler parts: br., brow tine; bz., bez tine; cr., antler crown; tr., trez tine.

(slightly flexed with flat parietals vs. strongly flexed with convex parietals), and antler morphology (Croitor 2006). This taxonomic approach has generated extensive debate (Pfeifer 1997; Di Stefano & Petronio 1998, 2002; Croitor & Bonifay 2001; Croitor 2006; Petronio et al. 2013). Pfeifer (1997) suggested classifying Pseudodama as a subgenus within Dama based on postcranial bone morphology. However, this proposal remains controversial since it relies on limb bones unassociated with cranial or antler material. Additionally, many authors question the monophyly of Pseudodama (Di Stefano & Petronio 1998, 2002; Croitor & Bonifay 2001; Croitor 2006; Petronio et al. 2013). Di Stefano & Petronio (2002) linked Villafranchian smallsized deer from Italy to modern Asian genera Axis and Rusa based on the general shape of three-pointed antlers. However, antler shape in this context reflects a universal evolutionary stage within Cervinae (Geist 1998) rather than a true phylogenetic relationship. Later, Petronio et al. (2013) placed Italian species in the genus Axis, interpreting them as advanced evolutionary stages. This classification is problematic, as Cervus nestii differs from Axis axis by its pronounced pearling, a trait shared with C. elaphus but absent in Axis. Furthermore, Dama eurygonos exhibits highly specialized cranial features, such as short, vertical pedicles and a rounded, flexed braincase (Croitor 2014). Cranial morphology is a key tool in zoological systematics, providing insights into the systematic and phylogenetic relationships among species, including cervids (Flerov 1952; Vislobokova 1990; Croitor 2006). Analysis of cranial features in “Dama-like” deer –such as braincase shape and flexion, orbital position, nasal bone length, pedicle orientation, presence of upper canines, and ethmoidal opening shape– led us to suggest that Pseudodama’s genotype species, Dama nestii nestii, closely resembles the European red deer (C. elaphus) (Croitor 2006; Croitor & Robinson 2020). This affinity is supported by antler traits, including a pearled surface and the transverse distal fork orientation of four-tined antlers. Hierarchical clustering of “Dama-like” deer with modern genera (C. elaphus, Dama dama, Rusa unicolor, and Axis axis) further supports these findings (Croitor & Robinson 2020). Results group Dama nestii nestii with C. elaphus, while Dama eurygonos aligns with modern fallow deer. Thus, we proposed that Pseudodama is a junior synonym for Cervus, and its type species should be reclassified as Cervus nestii (Croitor 2006; Croitor & Robinson 2020). Some authors (Breda & Lister 2013; Cherin et al. 2022) continue however to use the genus name Pseudodama. Cervus nestii is a relatively small-sized deer with a body mass of approximately 60 kg. It has four-pointed antlers that terminate in a simple fork, oriented more or less transversely with respect to the body axis (Fig. 3A). This distinctive crown shape is shared by C. nestii with the earliest Middle Pleistocene BA DC fig. 2. — Antlers of Eurasian wapiti and wapiti-like deer: A, Cervus magnus (Zsansky, 1925) from the Early Pleistocene of China; B, antler of an extant MacNeill’s stag Cervus canadensis macneilli Lyddeker, 1909; C, Cervus canadensis cherskii Boeskorov, 2005 from the Late Pleistocene of Siberia; D, Cervus canadensis combrayicus Croitor, 2020 from the Late Pleistocene of France, the median side of left antler.

The antler crown bauplan has important taxonomical significance in distinguishing between C. elaphus and C. canadensis (Beninde 1937; Flerov 1952; Sokolov 1959; Geist 1998). This difference in the pattern of the distal portion of the antler construction is already evident in C. nestii and C. magnus. Therefore, the difference in construction and development of the crown part in C. elaphus and C. canadensis indicates an independent evolutionary development of the antler crown in Cervus starting from the three-pointed antler stage. The third modern species, Cervus nippon, represents the four-point antler evolutionary stage like C. magnus and, according to mitochondrial DNA analysis, shows a closer phylogenetic relationship with C. canadensis than with C. elaphus (Kuwayama & Ozawa 2000; Pitra et al. 2004; Ludt et al. 2004). The early evolutionary split of the magnus-canadensis and nestii-elaphus lineages prompts the question of how red deer and wapiti acquired the second proximal tine of their antlers, known as the bez tine. The most plausible explanation is that there was genetic exchange between these two lineages, a phenomenon commonly observed in the animal world (Arnold 2015). Multiple cases of such interspecific gene exchange within the Cervus lineage were reported by Hu et al. (2019). It appears that the small homology of the bez tine is also found in some specimens of modern Rusa unicolor, as seen, for instance, in the antlers of this deer figured by Cuvier (1823: pl. 5, figs 59, 60). RED DEER CERVUS ELAPHUS Cervus elaphus is a relatively old, highly successful, and adaptable species, primarily thriving in broadleaf forest biomes across the middle latitudes of western Eurasia (Geist 1998; Di Stephano & Petronio 2021). Several distinctive cranial features distinguish this species. The facial portion of the skull in largest subspecies (as, for instance, in C. elaphus maral Ogilby, 1840), is elongated, primarily due to the lengthening of the orbitofrontal portion, with the anterior edge of the orbit projecting behind the posterior edge of the upper third molar, M3 (Ogilby 1840). The lower mandible also displays elongated characteristics: its diastemal part is relatively long and attains from 63.0 % to 82.5 % of the lower toothrow length, the angle between the horizontal and ascending ramuses is more open compared to other deer species, and the processus angularis is poorly pronounced. The lower fourth premolar typically exhibits molarization, although this trait can vary. The earliest fossil records of red deer date back to the early Middle Pleistocene of Europe, around 900 000 years ago. The earliest red deer, described as subspecies C. elaphus acoronatus, is characterized by the development of a simple distal fork and a very strong and long bez tine (Figs 3B, 4A). This subspecies is one of the largest forms of red deer, with an average weight estimated at c. 240 kg. It has been identified in England, Germany (including remains of young individuals reported as Cervus elaphoides Kahlke, 1960, and Cervus reichenaui Kahlke, 1996), France, Italy, the Netherlands, and Moldova (Beninde 1937; Lister 1990; Di Stefano & Petronio 1992). The early acoronate red deer evolved into several specialized endemic European subspecies, characterized by further complication of antler crown or specific evolutionary specializations in the case of Mediterranean dwarfed forms (Beninde 1937; Azzaroli 1961; Di Stephano & Petronio 2021). Between 600 000 and 500 000 years ago, European red deer began to evolve a multiaxial antler crown. The initial simple antler crown consisted of three tines. This evolutionary stage of red deer was identified as C. elaphus antiqui Pohlig, 1892. In France, evidence of early crowned deer dates back to around 400 000 years ago at the site of La Caune de l’Arago (Pyrénées Orientales) (Magniez et al. 2013). The evolution of C. elaphus angulatus Beninde, 1937 (occurring at the end of the Middle Pleistocene in Germany, approximately 250 000 years ago) is marked by further complication of the distal portion of the antler. The primary evolutionary development of C. elaphus angulatus is the emergence of a third B AC fig. 3. — Antler bauplan of red deer and its Early Pleistocene small-sized relative, frontal view: A, Cervus nestii (Azzaroli, 1947) n. comb.

Furthermore, specific features such as the strongly divergent antler beams and the downward direction of the middle (trez) tine led to the description of the wapiti from Saint-Hippolyte as a new subspecies, C. canadensis combrayicus Croitor, 2020 (Croitor 2020a). The antlers of the wapiti from Saint-Hippolyte exhibit a higher degree of evolutionary specialization compared to those of C. canadensis specimens from the Late Paleolithic site of Climăuți II, Moldova (Croitor & Obada 2018). The wapiti antler from Climăuți II is virtually indistinguishable from those of C. canadensis cherskii Boeskorov, 2005, originating from the Upper Pleistocene of Eastern Siberia, and C. canadensis mongoliae (Gaudry, 1872) (= C. canadensis fossilis Zdansky, 1925), found in the Upper Pleistocene of Northeastern China. The presence of C. canadensis in Europe during the cold phases of the Late Pleistocene is confirmed by paleogenetic studies revealing a close relationship between the modern Asian wapiti C. canadensis sibiricus / songaricus with the Late Pleistocene C. canadensis cherskii (Fig. 2C) and pre-Last Glacial Maximum specimens from Romania and Crimea (Stankovic et al. 2011; Meiri et al. 2018). Stankovic et al. (2011) consider the arrival of wapiti in Crimea as part of the invasion of cold-adapted forms into Eastern Europe at the end of the Würm II/Würm III Interstadial period (= MIS 3-MIS 2). The beam circumference and antler length of C. canadensis cherskii, C. canadensis combrayicus, and C. canadensis mongoliae place these fossil forms among the rare, exceptionally robust antlers observed in modern North American wapiti (Fig. 6). This remarkable robustness of antlers in both extinct wapiti forms and some modern individuals from North America may have diagnostic taxonomic significance. Unfortunately, the exact provenience of the specimens measured by Ward (1892) is not always available, making it impossible to provide a reliable interpretation of the exceptionally robust antlers from modern wapiti. Summarizing all the diversity of fossil and sub-fossil specimens we identified as wapiti in Western Europe, we propose the following subspecies and forms: – C. canadensis spelaeus (Owen, 1846) n. comb. (originally published as Cervus (Strongyloceros) spelaeus Owen, 1846), also known as the cave stag, from the Upper Pleistocene of England (MIS 3-MIS 2). Limited material makes it challenging to distinguish this wapiti subspecies. The primary characteristic available is the exceptionally large size of its antlers. The subspecies name spelaeus is retained mostly for historical reasons and lacks practical taxonomical or systematical significance; – C. canadensis combrayicus, from the Late Pleistocene of France. Unlike modern wapitis, this subspecies exhibits adaptations to open landscapes: its antlers spread strongly sideways, with the middle (trez) tine pointing downward, possibly serving a function similar to the posterior tine in the giant deer Megaloceros giganteus. The crown part of the wapiti from Saint-Hippolyte appears relatively weak, possibly due to the young age of the animal (Fig. 2D); – The isolated population of wapiti from the Holocene postglacial refugium in Sweden (Fig. 7A). This wapiti form is insufficiently described, as its remains are seemingly mixed with those of Holocene red deer C. elaphus (Ahlen 1965). The antlers of the remnant Holocene population of wapiti are palmated and resemble those of C. canadensis palmidactyloceros (De Stephano, 1911) n. comb.; – C. canadensis palmidactyloceros (originally published as C. elaphus palmidactyloceros De Stefano, 1911), from the Upper Pleistocene and early Holocene of Northeastern Italy, the Apennine Mountains, and Swiss peat bogs (Abbazzi 1995 also referred there as C. elaphus). This well-distinguished subspecies of wapiti survived into the Holocene in the AlpineApennine refugium (Croitor 2020a). The distal part of its antlers became strongly flattened and even palmated, with the first crown tine bifurcated (Fig. 7B). To some extent, this extinct form of wapiti exhibits parallelism with the North American C. canadensis merriami in the development of antler palmation; – C. canadensis tyrrhenicus (Azzaroli, 1961) n. comb. (originally published a Cervus tyrrhenicus Azzaroli, 1961), a subfossil dwarfed wapiti from the island of Capri, that we consider derived from C. canadensis palmidactyloceros (Croitor 2020a). Capri, intermittently connected to the Italian mainland, likely isolated the wapiti population after sea level rise in the Holocene. Evolutionary changes primarily affected the body size of C. canadensis tyrrhenicus, which did not exceed 100 kg. Its antlers lost the bez tine and the third crown tine but retained the bifurcated first crown tine and distal palmation (Fig. 7C). Therefore, a thorough revision of some Cervus remains from the Late Pleistocene of Europe, especially those associated with cold faunas, is necessary. The occurrence of the cold-adapted C. canadensis in Europe during the Last Glacial Maximum explains the “paradoxical” presence of elaphine deer in the southern extension of permafrost areas in Eastern Europe, notably in the Late Paleolithic sites Rașcov 7 and Cosouți in Moldova (Sommer & Nadachowski 2006; Sommer et al. 2008). Banks et al. (2008) developed ecological niche models of red deer during the Last Glacial Maximum that do not support the hypothesis of the “East Carpathian Last Glacial Maximum refugium” of C. elaphus. The confusing reports of red deer presence in the Eastern Carpathian area stem from David (1980), where some cervid remains are misidentified or their stratigraphic positions erroneously indicated. For example, the presence of C. elaphus at the Late Paleolithic site of Rașcov 7 is based on a talus that actually belongs to Ovibos moschatus (Zimmermann, 1780) (Croitor 2020b). The postglacial “red deer” remains studied by Drucker et al. (2011) from the Alpine environments of the French Jura, where it persisted in open landscapes and relatively cool conditions, most likely also belong to the remnant population of C. canadensis that survived during the early stages of the Holocene in the Alpine refugium. The remarkably elongated mandible’s well-preserved horizontal ramus from an unknown deposit level of Soleilhac (Haute-Loire; central France), described as Megaceros solilhacus Azzaroli, 1979, most probably belongs to C. canadensis. One of such specimens 157 ANTHROPOZOOLOGICA • 2025 • 60 (11) From continents to islands: tracking the red deer and its “troublesome cousin”, the wapiti, in Europe is the mandible 2003-4-420-SOL from Soleilhac that was originally described as Megaceros (Megaceroides) solilhacus (= Praemegaceros solilhacus) by Azzaroli (1979: pl. 3, fig. 2). It is characterized by a very long diastema, which attains 82.6 % of the lower tooth row length, approaching to the highest values of C. elaphus, and significantly longer than in species of the genus Praemegaceros (Croitor 2018). It is possible that the large-sized deer, C. elaphus sp., discovered in the upper levels of Combe-Grenal (layers 35 to 1; MIS 4; Guadelli 1997), is also a wapiti. RED DEER VERSUS WAPITI The morphological distinctions between wapiti and red deer pose a significant challenge. Comparative morphological studies of C. elaphus and C. canadensis have been limited, likely because these species were long regarded as groups of subspecies within the single species C. elaphus. Research efforts primarily focused on antler shape and linear cranial measurements, considered taxonomic criteria at the subspecies level (Heptner & Zalkin 1947). Consequently, available data on the morphological differences between these two species are scarce and incomplete, while size distinctions alone may be insufficient as a criterion. A comprehensive comparative study of cranial and dental morphology between wapiti and red deer has yet to be conducted. We found antler size, frequently cited by many authors as a key distinguishing feature between C. elaphus and C. canadensis, to be a statistically significant trait. Large datasets of hunting trophy antlers from red deer and wapiti, measured by Ward (1892), provide an excellent source for evaluating antler size (Table 1). The bivariate plot highlights a clear distinction in antler size between modern C. elaphus and C. canadensis, with fossil forms of wapiti exhibiting notably more robust antlers (Fig. 6). Our Student’s t-test analysis revealed significant statistical differences in both antler length and beam circumference measured above the bez tine, with a p-value extremely close to 0 (Table 2). This suggests that antler beam circumference is a reliable character for species identification. The regression model based on Ward’s (1892) measurements of C. elaphus antlers demonstrate a good fit, with an R² value of 0.67, indicating that 67 % of the variation in antler length (L) is explained by variation in antler circumtable 2. — Results of Student’s t-test comparing antler beam circumference and antler length of various subspecies of Cervus elaphus Linnaeus, 1758 and Cervus canadensis Erxleben, 1777 from North America.

Additionally, Pearson’s R of 0.82 suggests a strong positive correlation between antler circumference and antler length in the available data. The regression model based on available measurements of C. canadensis from North America is less accurate, with an R² value of 0.32 (Fig. 5), indicating that approximately 32 % of the variation in antler length can be explained by antler circumference in our model. Pearson’s R of 0.57 suggests a moderate positive correlation between these two variables. When interpreting the results of this linear regression, it is important to consider that the dataset consists of hunter trophies (Ward 1892), meaning the sample is artificially selected, which may influence the observed relationship between antler parameters. Additionally, the sample likely represents a mixture of antlers from different subspecies, further contributing to variability in the data. The equations of linear regression between antler beam robustness and antler length show that in modern wapiti, antler robustness increases more rapidly with increasing antler length (even after excluding a few exceptionally robust antlers as outliers that distorted the linear regression) than in red deer (Fig. 5). Distinctive features in antler morphology are well-documented. Antlers of C. canadensis differ from those of C. elaphus by their generally less developed crown, typically consisting of three tines arranged in the parasagittal plane (Lydekker 1898; Heptner & Zalkin 1947; Geist 1998). Wapiti antler crowns rarely evolve additional tines, although they may become somewhat compressed from the sides and often exhibit palmations under optimal environmental conditions (Heptner & Zalkin 1947). For example, the type specimen of C. canadensis merriami from Arizona showcases such a variant with a flattened distal portion of the antler (Nelson 1902). The position of the trez tine is a good diagnostic character that distinguishes wapiti from red deer. In C. canadensis, the trez tine is inserted on the lateral side of the beam, and the plane of trez ramification is clearly situated in a different plane with respect to the parasagittal plane of the crown tines and the brow and bez tines that are set on the anterior side of the beam. The smooth surface of the distal portion of the antler represents another specific morphological feature of wapiti distinguishing it from the completely pearled antlers of the red deer C. elaphus (Geist 1998). Partially pearled antlers are also reported for modern C. canadensis from Yakutia, Russia, evolving surface pearling only in the area of brow and bez tines (Stepanova & Argunov 2016). We have limited knowledge regarding morphological distinctions in cranial morphology between red deer and wapiti. Heptner & Zalkin (1947) noted some general differences in cranial proportions of modern C. canadensis and C. elaphus: wapiti skulls are typically broader and more robust with a somewhat shorter facial part. The ratio of the face length, measured from the anterior part of the orbit rim to the tips of the premaxillary bones (prosthion), to the condylobasal length is generally below 60 % in wapiti, while in red deer, this ratio is typically above 60 %, especially in the largest red deer subspecies C. elaphus maral, although there is some overlap in the sample values (Heptner & Zalkin 1947). From earlier descriptions of fossil wapiti or “large elaphoid” deer, we can identify the following dental morphological characters distinguishing the presumed fossil wapiti from European red deer: rugosity of enamel in cheek teeth, a strong entostyle in upper molars, relatively linguolabially broader upper molars, and a more frequent lingual groove in P2 (Pomel 1853; Gaudry 1876; Guadelli 1997). Biometric analysis of skeletal remains is a methodologically reliable approach, as size differences between C. elaphus and C. canadensis seem to be statistically significant (Prat & Suire 1971; Guadelli 1997). Additionally, interesting insights may arise from differential statistical analysis of postcranial remains, as well as measurements of pearl-like upper canine beads used as adornments in Paleolithic societies. The upper canines of red deer and wapiti are also distinguishable by their size (Covalenco & Croitor 2022). DISTRIBUTION OF RED DEER AND WAPITI IN EURASIA The red deer and the wapiti, primarily distributed across the Holarctic region, exhibit fairly similar morphology. Both belong to the genus Cervus, which emerged in the early Quaternary around 2.6 million years ago. Their evolution and differentiation into two distinct species began in Asia. While the red deer experienced significant expansion in Europe, the wapiti, originating from eastern Asia, colonized North America. However, during the Pleistocene, the wapiti also migrated to Western Europe, where its fossilized remains are now identified. The red deer, C. elaphus, thrives in deciduous and coniferous forest environments but also adapts to open spaces such as grasslands and is capable of colonizing high mountain valleys (Heptner & Zalkin 1947; Flerov 1952; Sokolov 1959). Its geographical distribution indicates dispersal from the Tarym area westward (Ludt et al. 2004). The earliest dispersal event occurred during the Early Pleistocene, marked by the presence of Cervus nestii in Georgia and Italy. By the early Middle Pleistocene, the paleontological record of Europe witnessed the dispersal of a larger species from the Glacial epoch, C. elaphus. Subspecies diversification and evolution of red deer during the Middle and Late Pleistocene are linked to Glacial refugia in the Iberian Peninsula, the Italian and Balkan Peninsulas, Anatolia, Transcaucasia, and Central Asia (Fig. 6). Thus, during glaciations, red deer acted as a typical warm-loving species, retracting its distribution to warm climate refugia. Glacial periods caused fragmentation of the red deer’s distribution area, initiating evolutionary differences between subspecies (Ludt et al. 2004). The evolutionary specialization of red deer subspecies increases from the east, where we find C. elaphus bactrianus with a simple terminal fork in the crown part of antlers and C. elaphus maral with a little branched crown and maintained spotting on the back in adult does, to 159 ANTHROPOZOOLOGICA • 2025 • 60 (11) From continents to islands: tracking the red deer and its “troublesome cousin”, the wapiti, in Europe the West, where the nominotypical subspecies C. elaphus elaphus evolved the most advanced antlers with a richly branched antler crown and completely lost white spots on the back in adults. This pattern is a common phenomenon in mammalian biogeography, where we often observe the most evolved forms occurring at greater distances from the center of initial evolution. The distribution dynamics of C. canadensis during the glacial periods diverged from those of C. elaphus. Geist (1998) characterizes wapitis as an eastern radiation of Cervus, migrating into dry, cold, continental regions and adapting to a grazing lifestyle in open landscapes. Modern wapiti subspecies encompass relatively primitive forms from mountainous areas of eastern Asia and more advanced forms from Siberia and North America. This distribution pattern reflects the relatively recent dispersals of wapiti from their initial area of distribution in eastern Asia to vast areas of northern Eurasia, coinciding with the onset of 40 000-year glacial cycles. The significant dispersal of C. canadensis in Siberia began during the Kargin interglacial, when wapiti reached the Far North of Asia (Boeskorov 2005). By the last Glacial Period, the distribution of Eurasian wapiti extended from the Far East to Europe. The arrival of wapiti in Europe coincided with the retreat of red deer to southern glacial refugia. The survival of wapiti in postglacial Europe is also linked to refugia, albeit different ones where relatively cold ecological conditions persisted, allowing them to avoid direct competition with C. elaphus. These refugia have been located in the Alpine and Scandinavian regions. The relatively abundant subfossil remains of C. canadensis palmidactyloceros from Switzerland and Italy, along with articulated skeletons with antlers from southern Sweden, suggest that the Alpine altitudes and Scandinavia likely served as postglacial refugia for wapiti in Western Europe. C. canadensis palmidactyloceros from Switzerland, Italy, and possibly the French Alps, represents a relict population of wapiti that survived in Europe despite Holocene climate warming (Croitor 2020a). Biogeographic, biological, and paleontological data suggest that C. elaphus and C. canadensis represent a typical example of vicarious species. The sharp geographical and genetic division between red deer and wapiti was established at least from pre-Last Glacial Maximum times (Meiri et al. 2018). The eastern border of the former species’ range and the western border of the latter’s shifted repeatedly eastwards and westwards with climate changes; thus, the dispersals of C. canadensis in Europe could have occurred several times (Stankovic et al. 2011; Meiri et al. 2018). Wapiti, along with Late Pleistocene horses and steppe bison, became extinct across the vast North Eurasian region after the last glaciation. The distribution area of the modern north Asian wapiti, C. canadensis sibiricus (including the darkercolored C. canadensis songaricus, which is often regarded as a junior synonym of sibiricus), is limited to the mountain ranges spanning from Tian-Shan and Altai to Sayan and the southern Transbaikal Area (Heptner & Zalkin 1947; Flerov 1952; Danilkin 1999). From a biogeographic standpoint, this suggests that the modern Siberian wapiti should be viewed as a remnant of the successful Ice Age megafaunal species, which managed to survive the Holocene climate warming in the mountains of Central Asia acting as a glacial refugium. According to Stankovic et al. (2011), the modern Altai environmental conditions, where Asian wapiti survived, represent a recent analogue of the environment during the full-glacial period of Central Europe. This assumption was supported by Pavelková Řičánková et al. (2014), who noted a marked ecological similarity between recent eastern Altai-Sayan mammalian assemblages and Pleistocene faunas. The Last Glacial and recent eastern Altai-Sayan faunal assemblages are characterized by the co-occurrence of large herbivore and predator species associated with steppe, desert, and alpine biomes. According to Pavelková Řičánková et al. (2014), relic glacial fauna seems to persist up to the present in the Eastern part of the Altai-Sayan region, where, for instance, reindeer and saiga antelope still live in sympatry. Hence, C. canadensis sibiricus is another member of this relic fauna that has persisted from the glacial epoch to the present day. CONCLUSIONS The discourse in scientific literature regarding the presence of wapiti (C. canadensis) in Europe during the Late Pleistocene has a longstanding history dating back to the first half of the 19th century. Over time, the accumulation of information on biology, evolution, dispersal, and ecology of both red deer and wapiti has led to a fresh perspective on this issue and identified the research directions that are imperative to pursue. Research in genomics and paleontology sheds light on the intricate taxonomy of both present-day and ancient cervids, along with their remarkable adaptive abilities. Recent paleontological updates have reshaped our understanding of the distribution patterns of both red deer and wapiti. During the Pleistocene epoch, according to our attribution of various specimens to the C. canadensis species instead of their original attribution to the C. elaphus species, wapiti expanded their range from Siberia to the far reaches of Western Europe, where they adapted to local conditions and diversified into various subspecies, including a smaller form that evolved in the condition of insular isolation. Scandinavia and the Alps acted as refuge areas at the transition from the Pleistocene to the Holocene, providing sanctuary for these species, which even reached as far as the Italian island of Capri. C. elaphus and C. canadensis occupy distinct ecological niches, underscoring the importance of accurately identifying fossil remains from prehistoric sites. This determination can offer insights into environmental conditions and hunting strategies, considering the differences in body size and ecological needs between the two species. Recent discoveries of fossil wapiti in Western Europe highlight the necessity of conducting comparative studies to distinguish diagnostic features between red deer and wapiti. Despite advancements, the natural history of the genus Cervus remains inadequately explored and warrants further attention from researchers. 160 ANTHROPOZOOLOGICA • 2025 • 60 (11) Croitor R. & Crégut-Bonnoure É.
