Answer to Question 1

a

Answer to Question 2

Natural selection is the key evolutionary mechanism  that all species produce offspring faster
than the food supply, that there is biological variation within all species, that in each generation
more offspring are born than survive, that more favorable traits lead to more fit individuals, that
the environment determines which traits are favorable, that traits are inherited and passed on to
yield greater reproductive success overall, that accumulations of changes over time may lead to a
new species, and that geographical isolation contributes to the formation of a new species through
selective pressure.
