The difference between us and Neanderthals is our creativity

The modern human brain and the Neanderthal brain began at about the same size at birth, but their skulls show that they began developing very differently within the first year of life, scientists say.

Neanderthals evolved more than 400,000 years ago, lived as hunter-gatherers in Europe and Asia, and went extinct about 30,000 years ago.

Judging by the archaeological record, Neanderthals were well-adapted to their particular environment, but they were not as creative in terms of hunting strategies or artwork – for example, they apparently did not make cave paintings the way their human contemporaries did.

Scientists at the Max Planck Institute for Evolutionary Anthropology scanned Neanderthals skulls and compared them with modern human skulls. Their results are published in the journal Current Biology.

Subtle changes in the early phases of brain development can have a huge impact on social cognition, communication, and how creative members of a species are, said study author Philipp Gunz of the  Planck Institute.

The pattern of brain development described in the study may point to a diminished inclination to communicate through art, and possibly also help explain why modern humans had advantages over Neanderthals, he said.
“If you are an artist you have to understand symbols, you have to understand meaning, you have to look at the world in the certain way, and it seems that Neanderthals, for 200,000 years, didn’t feel like it,” Gunz said.
