A tiny mutation in a gene common to mammals may have changed the destiny of humanity. The gene, Fox-P2—identified by British researchers two years ago—could have been the switch that lit up art, culture and social behaviors in Homo sapiens 50,000 years ago. Richard Klein, an anthropologist at Stanford University in California, said that early modern humans 100,000 years ago were confined to Africa and seemed no different from their now-extinct cousins Homo Neanderthalensis and Homo Erectus in Europe and Asia. Then, 50,000 years ago, behavior altered dramatically: “There was a biological change, a genetic mutation of some kind that promoted the fully modern ability to create and innovate. ” “When you look at the archaeological record before 50,000 years age, it is remarkable homogeneous. There are no geographically delineated groups of artifacts. Suddenly, modern-looking people began to behave in a modern ways, producing art and jewelry … manufacturing styles and different cultures.” Anthropologists have argued for years about this. Some researchers say population increase triggered creativity.
