Question 1

Which of the following BEST describes why the process of evolution is easier to study in fruit flies than in birds?

Fruit flies have a much shorter generation time than birds.

Fruit flies are smaller than birds.

Fruit flies have a simpler diet than birds.

Fruit flies do not live as long as birds.

Question 2

Which of the following statements represents evidence that supports the theory of common descent, but specifically contradicts the hypothesis of separate types?

The fossil record provides substantial evidence that humans and chimps share a common ancestor.

Radiometric dating methods show that Earth is billions of years old.

Many genes found in humans are also found in mold, and they perform the same function in mold that they do in humans.

The fossil record provides copious unequivocal evidence that the species that inhabit Earth have changed dramatically over time.

Question 3

Group 1: whale, giant fruit bat, giant walking stick (an insect); Group 2: penguin, ostrich, human; Group 3: hummingbird, bee, water strider bug

Group 1: penguin, ostrich, hummingbird; Group 2: water strider bug, giant walking stick (an insect); Group 3: whale, human, giant fruit bat

Group 1: hummingbird, ostrich, bee; Group 2: whale, human, penguin; Group 3: giant walking stick (an insect), water strider bug, giant fruit bat

Group 1: penguin, water strider bug, whale; Group 2: ostrich, giant walking stick (an insect), human; Group 3: hummingbird, bee, giant fruit bat

Question 4

Which of the following statements about the gene pool of a species is TRUE?

The genes in a species are only part of a universal gene pool that encompasses all species.

The gene pool is different in different individuals of the same species.

Every individual of a species carries part of the gene pool for that species in its chromosomes.

Every individual of a species carries the whole gene pool for that species in its chromosomes.

Question 5

Question 9

Consider what you have learned about natural selection and mutation concerning health issues like TB and head lice, and apply it to pesticide use and farming. Explain what is meant by a "pesticide treadmill" and why it is a concern to farmers and consumers.

Your response should be at least 200 words in length.
