Researchers discover evidence of the technology & behaviors linked to the emergence of human species

(George Washington University) An anthropology professor from the George Washington University and a team of international collaborators, including scientists from the Smithsonian's National Museum of National History, have discovered that early humans in East Africa used coloring materials and obtained a range of raw materials from distant sources-- activities which imply the existence of social networks--about 320,000 years ago, much earlier than previously thought.
