Human evolution
A bush, not a ladder.
The record
Several hominin species coexisted at various times, and our lineage is a branching bush rather than a single march of progress. Neanderthals and Denisovans left DNA in living people.
- Bipedalism came long before large brains.
- Race is not a biological division: variation within groups exceeds that between them.
Still going
Human evolution has not stopped. Lactose tolerance, altitude adaptation and malaria resistance all spread within the last ten thousand years.
