Regardless of the trigger, though, the fossils show that a «mammalian pattern of brain organization is apparent at this very early stage of proto - mammalian evolution,» Deacon says.

Although meat eating helped to shape the evolution of human brains, behavior and toolmaking, our early ancestors seem to have been better scavengers than hunters

According to her model, early in their evolution humans added cooperative breeding behaviors to their already existing advanced ape cognition, leading to a powerful combination of smarts and sociality that fueled even bigger brains, the evolution of language, and unprecedented levels of cooperation.

New research suggests that advances in the production of Early Stone Age tools had less to do with the evolution of language and more to do with the brain networks involved in modern piano playing.
