Homo sapiens (wise men), or Cro-Magnons, emerged 150,000 years ago in Africa with only 150,000 adults there, and 100,000 years ago moved out of Africa, arriving in Asia and Australasia 60,000 years ago and Europe 40,000 years ago. They showed racial diversity, but were more similar across the world than African gorillas meeting each other a short walk apart. Homeo sapiens have always been very creative, technological, conscious, using a complex language far beyond the immediate environment, originally developed through social networks, information in words and art about what and where to hunt and the best places to live. For 30,000 years homo sapiens have been the only human species.
