The process by which a species
becomes better suited to its
environment is known as
The theory of natural selection states
that
A.
Some live & some die in each
generation
B. Only the largest and strongest
survive
C. Random assortment of genes
results in better
characteristics in the
following generations
D. The best adapted individuals
survive and reproduce,
contributing the most genes
to the next generation
E. Individuals that mutate in
response to their
environment will survive

The cold weather would
cause a mutation in squirrels
which causes their fur to be
white
If a mutation occurred which
caused white fur to develop,
such white squirrels would
have a better chance to
survive and produce more
offspring with the
characteristic
Evolution would definitely
occur resulting in white
squirrels
