Data related to the study of the meat diet more than 1.2 million years ago are scarce because there are few sites of these chronologies and, in addition, research has always focused mainly on large animals. However, thesmall wildlife remains, such as birds, rodents, frogs, or turtles, are frequent in the deposits of this period. “Their presence has often been interpreted as the result of accumulations of natural origin or the product of intrusions of carnivores and birds of prey in the caves. Although these cases exist, in the Sima del Elefante we have been able to identify human groups as directly responsible of the presence of some of these small animals “, explains Blasco, who publishes his conclusions in the magazineJournal of Human Evolution.
Similar cases have been identified only in Africa, specifically in the East Lake Turkana reservoirs, during the same period. With later chronologies, human consumption of turtles is recorded more frequently not only in Europe, but also in the Middle East and Africa.
The remains of tortoises used for nutritional purposes, together with the remains of a rabbit and a bird also eaten by humans at other stratigraphic levels with similar chronologies and large prey, suggest ageneralist behavior regarding the meat diet, “which could have been one of thekeys to the success of the first hominids that colonized Europe more than a million years ago“, remarks the IPHES researcher.
