Cro Magnons were the first anatomically modern humans to inhabit Europe, approximately 40,000 years ago. They were known for their advanced technology, creative art and impressive hunting abilities. Synonyms for these ancient humans include early modern humans, Homo sapiens sapiens, and simply modern humans. Some scientists differentiate between anatomically modern humans and behaviorally modern humans. Anatomically modern humans refer to humans who possess physically identical features to current humans. Behaviorally modern humans refer to humans who display cognitive development and exhibit complex social and cultural behavior. Cro Magnons were behaviorally and anatomically modern humans, who played an important role in shaping human history and evolution.
