Taxonomic over-splitting of extinct or endangered taxa, due to an incomplete knowledge of both skeletal morphological variability and the geographical ranges of past populations, continues to confuse ...the link between isolated extant populations and their ancestors. This is particularly problematic with the genus Equus. To more reliably determine the evolution and phylogeographic history of the endangered Asiatic wild ass, we studied the genetic diversity and inter-relationships of both extinct and extant populations over the last 100,000 years, including samples throughout its previous range from Western Europe to Southwest and East Asia. Using 229 bp of the mitochondrial hypervariable region, an approach which allowed the inclusion of information from extremely poorly preserved ancient samples, we classify all non-African wild asses into eleven clades that show a clear phylogeographic structure revealing their phylogenetic history. This study places the extinct European wild ass, E. hydruntinus, the phylogeny of which has been debated since the end of the 19th century, into its phylogenetic context within the Asiatic wild asses and reveals recent mitochondrial introgression between populations currently regarded as separate species. The phylogeographic organization of clades resulting from these efforts can be used not only to improve future taxonomic determination of a poorly characterized group of equids, but also to identify historic ranges, interbreeding events between various populations, and the impact of ancient climatic changes. In addition, appropriately placing extant relict populations into a broader phylogeographic and genetic context can better inform ongoing conservation strategies for this highly-endangered species.

An experimental program of uniaxial compression forces on fresh and dry salmonid vertebrae of different sizes is presented to show what diagnostic features compression generates on these bones. The ...study found that diagnostic features exist, but their frequency often depends on size and the amount of fat that vertebrae contain when subjected to uniaxial compression. These signatures provide reference tools to assess formation processes of fish bone assemblages, whether archaeological or paleontological. The experimental data were later applied to a case study of a salmonid assemblage from the Late Upper Paleolithic to Mesolithic site of Santa Catalina (Basque country, Spain), to assess the validity of a hypothesis postulating that prehistoric salmonid populations from the Cantabrian region were subjected to overexploitation and that this phenomenon brought about a decrease in the mean size of specimens before the onset of the Neolithic in the region.

Numerous studies along the northern Mediterranean borderland have documented the use of shellfish by Neanderthals but none of these finds are prior to Marine Isotopic Stage 3 (MIS 3). In this paper ...we present evidence that gathering and consumption of mollusks can now be traced back to the lowest level of the archaeological sequence at Bajondillo Cave (Málaga, Spain), dated during the MIS 6. The paper describes the taxonomical and taphonomical features of the mollusk assemblages from this level Bj(19) and briefly touches upon those retrieved in levels Bj(18) (MIS 5) and Bj(17) (MIS 4), evidencing a continuity of the shellfishing activity that reaches to MIS 3. This evidence is substantiated on 29 datings through radiocarbon, thermoluminescence and U series methods. Obtained dates and paleoenvironmental records from the cave include isotopic, pollen, lithostratigraphic and sedimentological analyses and they are fully coherent with paleoclimate conditions expected for the different stages. We conclude that described use of shellfish resources by Neanderthals (H. neanderthalensis) in Southern Spain started ∼150 ka and were almost contemporaneous to Pinnacle Point (South Africa), when shellfishing is first documented in archaic modern humans.

Abstract Muslim religion has strict rules to determine what kinds of foodstuffs, and under what circumstances, are deemed appropriate for consumption. Fishes are not an exception to this rule and ...features such as body shape or the presence and conspicuousness of scales dictate whether certain species are acceptable or rejected. In this paper, an overview of the Iberian ichthyoarchaeological record from Muslim sites is presented to ascertain whether differences with Christian sites existed in terms of these characters and to what extent these allow one to take fish assemblages as cultural proxies of archaeological deposits. In the case of coastal (production) sites, we also consider whether the peculiarities a given fish assemblage exhibit reflect instead certain environmental features such as the biotopes where a given local fishery operated.

Archaeologists often argue whether Paleolithic works of art, cave paintings in particular, constitute reflections of the natural environment of humans at the time. They also debate the extent to ...which these paintings actually contain creative artistic expression, reflect the phenotypic variation of the surrounding environment, or focus on rare phenotypes. The famous paintings "The Dappled Horses of Pech-Merle," depicting spotted horses on the walls of a cave in Pech-Merle, France, date back ∼25,000 y, but the coat pattern portrayed in these paintings is remarkably similar to a pattern known as "leopard" in modern horses. We have genotyped nine coat-color loci in 31 predomestic horses from Siberia, Eastern and Western Europe, and the Iberian Peninsula. Eighteen horses had bay coat color, seven were black, and six shared an allele associated with the leopard complex spotting (LP), representing the only spotted phenotype that has been discovered in wild, predomestic horses thus far. LP was detected in four Pleistocene and two Copper Age samples from Western and Eastern Europe, respectively. In contrast, this phenotype was absent from predomestic Siberian horses. Thus, all horse color phenotypes that seem to be distinguishable in cave paintings have now been found to exist in prehistoric horse populations, suggesting that cave paintings of this species represent remarkably realistic depictions of the animals shown. This finding lends support to hypotheses arguing that cave paintings might have contained less of a symbolic or transcendental connotation than often assumed.

The number of exotic animal species that were introduced in Iberia during the Middle Ages constitute a defectively documented area of research, mostly addressed through historiographic methods. In ...this paper we evidence that even in the case of large, exotic animals exchanged as gifts among dignitaries the documentary data can be painfully incomplete. This is the case of the animal embassy that the Mamluk sultan Baybars al Bunduqdari sent in 1261 to the Castilian king Alfonso X. Although the written sources do not specify the complete list of species nor the reasons for mentioning some but not others, documentary and iconographic data suggest that, in addition to an elephant, a giraffe and a zebra, this lot included, in a decreasing order of probability, a lion, a dromedary, an ostrich, and a Nile crocodile. If such conspicuous beasts could pass unnoticed in a royal chronicle, one may contend that even in the most thoroughly documented cases, written sources may refer but a minimal fraction of the animals translocated into Iberia during the Medieval period. Such information vacuum stresses the difficulties of granting “indigenous” status to species traditionally assumed to constitute elements of the Iberian fauna when their historical contingencies are defectively known, a matter of concern for the current rewilding debate in Spain.
Data from morphology, linguistics, history, and archaeology have all been used to trace the dispersal of chickens from Asian domestication centers to their current global distribution. Each provides ...a unique perspective which can aid in the reconstruction of prehistory. This study expands on previous investigations by adding a temporal component from ancient DNA and, in some cases, direct dating of bones of individual chickens from a variety of sites in Europe, the Pacific, and the Americas. The results from the ancient DNA analyses of forty-eight archaeologically derived chicken bones provide support for archaeological hypotheses about the prehistoric human transport of chickens. Haplogroup E mtDNA signatures have been amplified from directly dated samples originating in Europe at 1000 B.P. and in the Pacific at 3000 B.P. indicating multiple prehistoric dispersals from a single Asian centre. These two dispersal pathways converged in the Americas where chickens were introduced both by Polynesians and later by Europeans. The results of this study also highlight the inappropriate application of the small stretch of D-loop, traditionally amplified for use in phylogenetic studies, to understanding discrete episodes of chicken translocation in the past. The results of this study lead to the proposal of four hypotheses which will require further scrutiny and rigorous future testing.
