Credit: University of Granada Creativity--the "secret weapon" of Homo sapiens--constituted a major advantage over Neanderthals and played an important role in the survival of the human species. This is the finding of an international team of scientists, led by the University of Granada (UGR), which has identified for the first time a series of 267 genes linked to creativity that differentiate Homo sapiens from Neanderthals. Molecular Psychiatry (Nature), suggests that it was these genetic differences linked to creativity that enabled Homo sapiens to eventually replace Neanderthals. It was creativity that gave Homo sapiens the edge, above and beyond the purely cognitive level, by facilitating superior adaptation to the environment compared to that of now-extinct hominids and providing greater resilience to ageing, injury, and disease.
