More competition for food

13.

Suppose a few brown mice had a mutation that resulted in a new allele that caused their fur to turn white in colder temperatures. Which of the following factors has the greatest effect on whether brown fur will become more common in mice population?

It will adapt and the birds that ate the medium sized seeds will learn to eat fish, insects, or other animals

b)

It will diverge into two species: one that eats small seeds and one that eats large seeds.

c)

It will permanently shrink to approximately 25% of its current size

d)

It will go extinct because there aren’t enough seeds to support all of the individuals

15.
Of the following, which is NOT part of Darwin's theory of natural selection?

Variations in a population exist and those variations are inherited. 
c)
Individuals with variations suitable to their environment have shorter lifespans and produce fewer offspring.
