Comparing the brain anatomy of fossil hominins and extant primates, the authors determine that strong covariation between different areas of the brain in Homo sapiens and Homo neanderthalensis evolved under higher evolutionary rates than in any other primate. Strong covariation is present in juvenile and adult H. sapiens, and in juvenile but not adult great apes.
