1. What type of selection was most important in selecting for the giraffes neck?

sexual selection

2. What is most likely to happen if an isolated population is isolated long enough?

The isolated population will eventually die out and become extinct. (2 different species can't reproduce)

3. Can acquired traits be inherited by offspring of an individual?

No

4. What type of fitness accounts for an individual having reproductive fitness even iif they don't reproduce?

kin selection (indirect or inclusive selection)

5. What living group of animals is thought to be the closest relative of humans?

chimps

6. What part of evolution tends to be very intuitive?

relational relatedness (offspring relation to parents)

7. What force of evolution causes changes in alleles of a population through the formation of new alleles?

mutations

8. What force of evolution is described as random changes in the alleles of a population over time?

genetic drift

9. What force of evolution is described as some alleles may have a benefit to reproduction through attractiveness or survival over time?

selection

10. What force of evolution accounts for changes of alleles in population from movement of alleles from or into another population?

gene flow
