1. 15-3 NOTES: EVOLUTION IN ACTION PP. 308-311

2. EVOLUTION DEFINED… Evolution of a population is due to environment and the interaction of other species

3. ARTIFICIAL SELECTION humans breed for specific traits causing differences in species (i.e. dog breeding)

4. TYPES OF EVOLUTION Convergent evolution: Organisms with very different ancestors become more alike due to a common environment (i.e fish and whales)- compare analogous structures

5. Ex: whale and fish, bird and insect

6. TYPES OF EVOLUTION Divergent evolution: populations become more and more dissimilar to adapt to the environment -compare homologous structures

7. Adaptive Radiation: Population undergoes divergent evolution until it fills all areas of the environment

10. EX: Rough-skinned newt and garter snake Newt evolved to produce neurotoxins then the snake evolved resistance to this toxin through genetic mutations. Birds and flowers, Humans and bacteria are other examples Birds and flowers, Humans and bacteria are other examples

11. COEVOLUTION When two species each evolve in response to each other over a long period of time. This leads to a close relationship
