The first physically modem humans, Homo sapiens, appeared in tropical Africa between 200,000 and 150,000 years ago-dates determined by molecular biologists and archaeologists working together.

To this day, scientists have no idea why hominids first appeared. It was, for a long time, assumed that tools made our ancestors what they were. This was a good guess and, millions of years later, tools did matter a lot. But big brains and tool use (technology, basically) wasn’t ...
