Evolution

4. process by which new species are created
8. the main mechanism of evolution
10. this type of evolution is when unrelated species evolve in similar ways from different ancestors, like birds and bats.
11. this type of evolution is when a population splits off and becomes a new species, the two are related but develop new traits for their environment
13. change in the gene pool of a population over time
14. the variety of living things in our environment
16. a product of the reproductive process
18. natural selection for courtship purposes
19. in example of mouse speciation what separated the mouse population
20. if genes mutate and individuals are selected then these evole
22. a group of individuals that can interbreed

1. along with ammonia it was the most abundant gas in the early atmosphere
2. when speciation occurs due to a geographic separation
3. all organisms share a tremendous similarities in this
5. credited with developing the theory of evolution
6. different species have different gene pools, this is called
7. the birds Darwin studied
9. selection when natural selection favors individuals that are like everyone else
12. when natural selection favors a single trait like color
15. along with selection and time shape how natural selection works
17. when a gene is copied incorrectly this occurs and may be good or bad
21. there are different varieties of these under the taxon species, they may interbreed.
