Changing environment
At the end of the Pliocene, and more strongly at the beginning of the Pleistocene, there is a spread of warm-season grasses that were resistant to increasingly drier climatic conditions. The selective pressure of such changes in the environment affected different adaptations in different evolutionary lines of hominins, and at the same time the first robust species of australopithecines appeared, as well as the first remains of the genus Homo.
Traces and the angle of wear of the teeth of the first members of the genus Homo speak of different adaptations and the exploitation of a wider range of food resources. One of the differences between the slightly later members of the genus Homo and the earlier and contemporaneous Australopithecines is that they had greater access to animal sources of protein
