Evolution

3. Darwin/ all life was "produced by a simple life filament"
6. Variation/ mutations are sources of different traits
8. some traits give a selective advantage
10. habitats separated
11. isolation/ bodies are incompatible for sexual reproduction
14. populations have ability to reproduce more individuals than can survive
18. a group of individuals tat belong to the same species live in a defined area, and breed with others in the group
20. isolation/ differing courtship prevent gene flow
21. populations-variations in traits; environmental influence
24. flow/ immigration or emigration between 2 or more populations

1. extinct glyptodonts- large, similar to armadillo and same region
2. changes in environmental conditions that lead to a phenotypic shift in one direction
4. changes happening over a long period or time
5. drift/ small populations affected by random change
7. differences in timing of reproduction
9. intermediate forms of the trait are elected against
11. body structures
12. ex: mating ritual
13. small scale changes within a population
15. functionality
16. Selection/ overpopulation,genetic variation, competition, successful reproduction
17. isolation/ early death, sterility, or low survival rates of hybrids
19. Lyell/ Theory of uniformity
22. mortality/ molecular incompatibilities
23. Breeding/ artificial selection
