The prehistoric site of Gesher Benot Ya'aqov in northern Israel has given archaeologists the earliest evidence of a social organization, of person-to-person communication, and divided work and living spaces, all of which are considered to be early milestones in of modern human behavior.
The site dates back to 750,000 years ago, and was most likely built by the species Homo erectus. Archaeologists have unearthed such items as several hand axes, scrapers, chopping tools, and even drills and hammers. Domesticated tasks such as seafood preparation and nut processing were apparently taking place at different sections of the site.
Previously the search for clues of modern human behavior was concentrated on Homo sapiens from the middle Stone Age, or about 300,000 to 50,000 years ago, but this site tells us that a more modern human behavior took place much earlier than that.
