Neanderthal exploitation of ibex and chamois in southwestern Europe

There is increasing evidence that Neanderthals had a diverse and flexible diet. They exploited a wide range of resources from large proboscideans to small animals like turtles, rabbits, and marine species. Here, we discuss the importance of ibex and chamois in Neanderthal hunting strategies. The exploitation of both animals has traditionally been regarded as typical of Homo sapiens hunting behavior but was not a feature of Neanderthal behavior, which was thought to have focused on other kinds of game like deer, horses or large bovids. Our analysis of an extensive sample of Middle Paleolithic sites with faunal remains in the Iberian Peninsula reveals that Iberian ibex and chamois were frequently present throughout this period. Statistical analyses allowed us to assess the conditions that might have favored the presence or absence of these animals in the sites, while the taphonomic analyses enabled us to address the issue of whether ibex and chamois were indeed hunted by Neanderthals in the Iberian Peninsula. Our results indicate a better representation of both species in rocky and mountainous areas. The taphonomy of some sites reveals that chamois and ibex were hunted by Neanderthals, who showed great adaptive capacities to a wide variety of environments, including mountainous habitats. In contrast, other sites with favorable ecological conditions for ibex and chamois where these animals were not exploited by Neanderthals, who chose to hunt other species like deer, horses or aurochs, suggest behavioral complexity and large versatility.
