What is artificial selection?

• The death of every member of a species

• A change in the structure or amount of the genetic material of an of an organism

• The human practice of breeding animals or plants that have certain desired traits

• The process which individuals that are better adapted to their environment and they survive and reproduce better than less adapted

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species

• Environmental Change

• Adaptation

• Variation

Two fossils that appear to be from the same type of organism are found in two different layers of rock. The layers of rock are shown below.

What can be determined from the location of the fossils?

• The prey of the organisms

• The predators of the organism

• The cause of death for the organisms

• The relative age of the organisms.
