Scientists find evidence of paint, complex tools and climate chaos at the dawn of humanity
Sarah Kaplan
In 320,000-year-old coloured rocks and sophisticated stone tools uncovered at an archaeological site in southern Kenya, scientists say they've found early evidence of what makes humans unique.
The rocks show signs of being ground up for paint pigment - an indicator of ancient communication. And the stone for the tools comes from sources dozens of kilometres away - suggesting trade. Meanwhile, sediment cores bear evidence of centuries of climate chaos - a sign that the site's inhabitants had to adapt to survive.
