Brain size of human ancestors evolved gradually over 3 million years

Brain size of human ancestors evolved gradually over 3 million years Modern humans have brains that are more than three times larger than our closest living relatives, chimpanzees and bonobos. Scientists don't agree on when and how this dramatic increase took place, but new analysis of 94 hominin fossils shows that average brain size increased gradually and consistently over the past three million years. http://ift.tt/eA8V8J
