Darwin's Journey and Natural Selection

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

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

• 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.

• 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.

• 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.

A fox with thicker fur than average would have a survival advantage over other foxes if:

• There is more competition for food in the fox population.

• The air temperature significantly decreases in winter.

• A drought occurs, limiting the amount of water available.

• A new disease appears that infects the foxes.
