Early Eurasian Humans Had Ape-Like Brains

Early humans still had great ape-like brains, according to a new study that found modern humans evolved to have our "advanced" thinking organs relatively recently, between 1.7 million and 1.5 million years ago.

The finding overturns a previously held view that humans' frontal lobe — the part of the brain that processes complex cognitive tasks, including social thought, tool use and language — developed at the transition from Australopithecus to Homo, which happened roughly 2.8 million to 2.5 million years ago, the researchers said.
