The Lower Paleolithic began with the appearance of the oldest stone tools in the world, roughly 3.3 million years ago in eastern Africa, which were produced by an as-yet undetermined hominin [REF].
The move from the mostly frugivorous or omnivorous diet of hominin Australopithecus to the carnivorous scavenging lifestyle of early Homo has been explained by the climate changes in East Africa associated with the Quaternary glaciation.
