Traditional views of Neanderthal hunting strategies envisage them preying on herd species such as bison and deer, rather than the sophisticated tracking of solitary animals. Analysis of faunal remains from El Esquilleu Cave in northern Spain, however, demonstrates that during certain periods of the Middle Palaeolithic occupation, Neanderthals focused on the hunting of ibex and chamois, small solitary species that inhabited the mountainous terrain around the site. These results indicate that Neanderthal hunting practices may have had more similarity to those of their Upper Palaeolithic relatives than is usually assumed.
