The brain is central to human evolution as its high metabolic cost drove specific physiological adaptations, such as those described in the 'expensive-tissue hypothesis' [1] and [2]. Furthermore, the evolution of larger brains in human ancestors is linked to dietary shifts like meat consumption [3].
