Humans and Evolution
Where Humans Fit
Humans as part of the tree of life
Humans are one species among many and share common ancestry with other primates. Our traits reflect evolution by the same processes that shape all other species.
What makes human evolution special
Human evolution includes bipedalism, large brains, tool use, language, culture, and long-term cooperation. These traits evolved over time and in interaction with changing environments.
Culture and biology
Human behavior is shaped by both biology and culture. Cultural evolution can spread ideas and behaviors much faster than genetic evolution.
Biological vs cultural inheritance
Biological inheritance
- Passed through DNA
- Usually changes over many generations
- Operates through reproduction

- Passed through learning and communication
- Can change rapidly
- Includes tools, language, and traditions
