Claim summary · not a verbatim quotation
The time span of human intelligence has increased from 50,000 years to over a million years based on recent evidence.
The finding
What the evidence shows
Researchers really have pushed back estimates for when modern human behavior and symbolic thought emerged, from the old 50,000 year 'human revolution' idea to evidence stretching back roughly 100,000 to 300,000 years in Africa. That's a genuine and major shift in the field, but mainstream research doesn't support stretching the timeline back over a million years.
