How Neanderthals Got Their Unusually Large Brains

Neanderthals had larger brains than modern humans do, and a new study of a Neanderthal child's skeleton now suggests this is because their brains spent more time growing.Modern humans are known for having unusually large brains for their size.It takes a lot of energy to develop such large brains, and previous research suggested that the high cost of modern-human brain development was a key reason why human growth in general is slow compared with that of other primates.
