Genes Found that May Explain Expansion of Higher Brain Function in Homo sapiens

In the study of human evolution, one conundrum has always vexed us: how did humans evolve such powerful brains? Few Differences in Chimp and Human DNA The genome of Homo sapiens is remarkably similar to those of  our closest extant relatives, the common chimpanzee (Pan troglodytes) and the pigmy chimpanzee, or bonobo (Pan paniscus). On the sequence level, we … More Genes Found that May Explain Expansion of Higher Brain Function in Homo sapiens
