4500 years of morphological diversification in Western Europe wild boars (Sus scrofa) and the consequences of the Neolithic transition (original) (raw)

2023, Quaternary Science reviews

Evolutionary biologists have recently solicited archaeologists to help document and understand the morphological evolution of animals in response to human activities and, more generally, to help reconstruct the history and significance of the anthropogenic impact on worldwide ecosystems. Artificial selection associated with domestication is the best-known example of a major anthropogenic morphological evolution preserved in the archaeological record. However, the impact of the domestication process and dispersal on the morphological evolution of animals has been far less explored. To fill this gap, we focused on 4500 years of evolution in Western Europe Sus scrofa, covering the Neolithic transitiona major anthropogenic ecological disturbance involving landscape modification and the translocation of domestic mammals. Using geometric morphometrics on key phenotypic markers preserved in the archaeological record, associated with isotopic studies, we explored how, and in response to which cultural drivers, the Neolithic niche construction has influenced the morphological evolution of Western European wild boars (Sus scrofa scrofa). The decoupling of size and shape components from bone morphological variation has facilitated the identification of several processes of phenotypic diversification of Sus s. scrofa in response to human behaviour during the Neolithic transition in Western Europe.

Epipaleolithic hunter-gatherers from the Near East introduced wild boars (Sus scrofa) to Cyprus, with the Early Pre-Pottery Neolithic (PPN) settlers hunting the wild descendants of these boars. However, the geographic origin of the Cypriot boar and how they were integrated into the earliest forms of pig husbandry remain unsolved. Here, we present data on 11,000 to 9000 cal. BP Sus scrofa from the PPN sites of Klimonas and Shillourokambos. We compared them to contemporaneous populations from the Near East and to Neolithic and modern populations in Corsica, exploring their origin and evolution using biosystematic signals from molar teeth and heel bones (calcanei), using 2D and 3D geometric morphometrics. We found that the Cypriot PPN lineage of Sus scrofa originates from the Northern Levant. Yet, their phenotypic idiosyncrasy suggest that they evolved into an insular sub-species that we named Sus scrofa circeus, referring to Circe, the metamorphosis goddess that changed Ulysses companions into pigs. The phenotypic homogeneity among PPNA Klimonas wild boars and managed populations of PPNB Shillourokambos suggests that local domestication has been undertaken on the endemic S. s. circeus, strengthening the idea that Cyprus was integrated into the core region of animal domestication.
