b. shrinking.
c. evolving.
d. not evolving.
9. In a species of snail, dark individuals are better hidden (from bird predators) in the
shady forest, while lighter individuals are better hidden in well lit brushy edge areas.
There are no areas of intermediate brightness; therefore, ___________ acts on shell
color in these snails.
a. directional selection
b. stabilizing selection
c. disruptive selection
10. What is the difference between evolution and natural selection?
a. Evolution is an outcome of natural selection.
b. This is best described as a change in the characteristics of a population over
time.
c. There is no difference because evolution and natural selection are the same.
d. The difference is that individuals evolve, while populations experience natural
selection
