Guppies are small fish that live in South American rivers. They can have different- sized spots on their bodies.

The river bottoms are covered in rocks. Guppies with spots that are the same size as the rocks on the bottom are harder for bigger fish to see and catch.

The diagram below shows a population of guppies that live in a river. At time 1, the population had the same number of guppies with small and large spots. At time 2, after many generations, there were many more guppies with small spots and fewer guppies with large spots in the population.


How did the environment change between time 1 and time 2? How did the population change?

a)

You cannot tell how the environment changed. With each generation, more guppies passed on the gene for small spots to their offspring.

b)

The rocks became smaller. With each generation, more guppies with small spots survived long enough to pass on the gene for small spots to their offspring.

c)

The rocks became smaller. Guppies with small spots are more likely to survive, so the guppies with large spots changed to have small spots.

d)

The rocks became smaller. Guppies with small spots are more likely to survive, so both kinds of guppies passed on the gene for small spots to their offspring.

Tree squirrels can have different fur colors.

Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur that is the same color as the trees are harder for the foxes to see and catch.

The diagram below shows a population of squirrels that live in a forest. At time 1, the population had the same number of black and gray squirrels. At time 2, after many generations, there were many more black squirrels and fewer gray squirrels in the population.

How did the environment change between time 1 and time 2? How did the population change?

a)

You cannot tell how the environment changed. With each generation, more squirrels passed on the gene for black fur to their offspring.

b)

There were more black trees. Squirrels with black fur are more likely to survive, so the squirrels with gray fur changed to have black fur.

c)

There were more black trees. Squirrels with black fur are more likely to survive, so both types of squirrels passed on the gene for black fur to their offspring.

d)

There were more black trees. With each generation, more squirrels with black fur survived long enough to pass on the gene for black fur to their offspring.
