DEEP ROOTS OF HUMAN BEHAVIOR

When did humans begin to use complex tools? (And why does it matter?)

The first tools made by our human ancestors were pieces of stone struck from larger lumps, then modified.

Then came a revolution: tools made of multiple parts.

Complex tools.

Objects that had never existed before, created by putting together separate parts using several different processes.

This revolutionary development occurred before we, Homo sapiens, emerged.

The inventor was our direct ancestor, Homo heidelbergensis, who lived in Africa 600,000-200,000 years ago and was probably, by then, using language and symbols.

When did this technological advance take place? Why was it so significant to our development as a species?

These are the deep roots of our human behaviour that we are investigating.
