Evolution

4. Whales and fish are an example of this type of evolution pattern.
5. Selecting a mate based upon desired traits.
6. This type of evolution pattern is responsible for the hummingbird's long tongue and the cardinal flower's thin tube shaped petals.
9. This type of natural selection pattern may quickly gives rise to two new species; both extreme phenotypes are favored by the environment.
10. If a species does not genetically adapt to the environment, they may go ___.
11. Moths and this animal have evolved in response to one another's adaptations.
13. This type of isolation prevent breeding due to the reproductive parts no longer fitting together.
16. Galapagos finches are an example of this evolution pattern.
17. Type of speciation that occurs as a result of a physical barrier preventing interbreeding of the two populations.

1. Could result from a natural disaster dramatically reducing the population size.
2. A random change in allele frequencies that occur in small populations.
3. Zebra and lion speed increase as a result of this type of evolution pattern.
7. Supported by homologous structures, species that have evolved through this pattern share a common ancestor.
8. Human birth weight and head size is a result of this type of selection pattern.
12. Type of speciation that occurs due to pre-zygotic reproductive isolation modes.
14. The result of two species breeding, often sterile.
15. Speciation always begins with this.
