One of the genes behind the dramatic evolutionary enlargement of the human brain has been identified. By greatly increasing the number of cells in important brain regions, the gene in question might have helped humans develop the cognitive abilities that are unrivalled in the animal kingdom.

In the study, published in the journal Science, researchers report that the gene can also be found in the DNA of our extinct relatives, Neanderthals and Denisovans, but not chimpanzees, who otherwise share 98.5 percent of our DNA.
