Question

Tree squirrels can have different fur colors.

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

[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.

The diagram below shows how the population changed after many generations.

How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.

Answer 1

The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.

How the trees became more black too? I have no idea, sorry.
