Cognitive Revolution Made Sapiens Significant
Until about 70,000 years ago humans were ecologically insignificant animals, but in East Africa Homo sapiens suddenly began cooperating in larger numbers and producing art, religion, and large-scale politics, then spread worldwide—reaching Australia ~50,000 years ago and the Americas ~15,000 years ago—within an evolutionarily short time.
