320,000 BC Stone Age Revolution

Scientists discover evidence of early human innovation, pushing back evolutionary timeline,
University of Utah, March 15, 2018.

"...The first evidence of human life in the Olorgesailie Basin comes from about 1.2 million years ago."

" 2002, the Human Origins Program team discovered a variety of smaller, more carefully shaped tools in the basin."

"...the tools were surprisingly old--made between 320,000and 305,000 years ago."

"...found small stone points made of non-local obsidian at their Middle Stone Age sites. The team also found larger, unshaped pieces of the sharp-edged volcanic stone at Olorgesailie, which has no obsidian source of its own."

"...early humans in eastern Africa had--by about 320,000 years ago--begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age."

"...coloring is often taken by archeologists as the root of complex symbolic communication,"

" to the oldest known fossil record of Homo sapiens and occur tens of thousands of years earlier than previous evidence from eastern Africa."

"...As earthquakes remodeled the landscape and climate fluctuated between wet and dry conditions, technological innovation, social exchange networks and early symbolic communication would have helped early humans survive and obtain the resources they needed despite unpredictable condition."



The Ancient History of Humans is shifting as rapidly as the Ancient History of our Universe. Both are undergoing revolutionary transitions as our understanding expands with the collection of new information, the increasing precision of our technological tools, and the difficulty of shedding long-held misconceptions.

The "dawn" of humanity, and our subsequent physical and technological evolutions, keeps getting earlier and earlier...
