Question

1. The famous biologist who is considered the father of evolution is________

2. What is natural selection?

3. A scientist is doing a field study in the Mojave Desert. She observes a type of rabbit that has very large and wide ears loaded with blood vessels. She hypothesizes that the large surface area of the ears aids in heat dissipation, thus cooling the rabbit off. What would the specialized ears of this rabbit be considered? Briefly explain your answer.

4. The similarities seen in certain species that result from common ancestry is known as _____________.

5. Identify three evidences for evolution.

6. What is the difference between homologous structures and vestigial structures?

7. True or false: Evolutionary trees show patterns of descent and are supported by homologous structures. If false, make it a correct statement.

8. List three key points about evolution by natural selection.

9. Compare and contrast artificial selection to natural selection.

10. Briefly explain how mutation allows for variation achieved by sexual reproduction.

11. List the three components of sexual reproduction that account for genetic variation.

12. What is a population?

13. ______________ consists of all copies of every type of allele at every locus in all members of the population.

14. A population of bacteria sees an increase in the number of bacteria resistant to a certain anti- biotic over a number of generations. This is known as ___________.

16. Which of the following best describes relative fitness?

a. The creation of new gene combinations.

b. Individuals migrating into and out of an area
