A shift in metabolic gear in our ancient ancestors means that humans burn calories much faster than any other primate, giving us energy for larger brains
The hefty brains that set humans apart from other apes came into being when our ancient ancestors massively ramped up their metabolism, scientists say.
The shift in metabolic gear, after the human lineage split from other primates, gave humans enough energy to run larger brains, have children in rapid succession, and live longer lives, the researchers found.
