Evolution (for the FINAL!)

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

The environment around Manchester, England, changed during the Industrial Revolution, darkening the trees. How did this change affect peppered moths living in the area?

• Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.

• Natural selection favored moths with white wings that were easy for predators to see.

• Natural selection favored moths with white wings because predators could not see them on the soot-colored trees.

• Natural selection caused moths with white wings to become extinct.

Evolution is best defined as:

• the process which organisms die.

• the process by which organisms change over time.

• the process which organisms that are extinct become revived.

• the process which non-living things fossilize.

What type of evidence for evolution is represented in the picture above:

• Fossils

• Vestigial Structures

• DNA

• Homologous Structures

What type of evidence for evolution is shown in this picture?

• Fossils

• Homologous Structures

• Vestigial Structures

• DNA

Adaptations are:

• never related to an organism's niche and environment.

• physical or behavioral characteristics that help an organisms survive and reproduce.

• physical or behavioral characteristics that do not help the organism in any way.

• genetic mutations that have gone wrong.

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population
