1
Q
Lamarck’s view
A
organisms appear randomly and start simple but become more complex
2
Q
how can complex traits evolve by random mutation
A
very small changes that cause simple changes that are adaptive but grow to become more complex
3
Q
the major transition in evolution
A
greater complexity arises from independent replication coming together
4
Q
unit of selection
A
traits that benefit the species may not be good for the individuals
5
Q
when is there cooperative adaptation
A
- high relatedness
- reciprocal altruism (when organisms repeatedly encounter each other)
6
Q
How do individual genomes stay cooperative
A
mitosis and meiosis
development and multicellularity
