Evolution is:
a)
change in the heritable traits of biological populations over successive generations.
b)
the change in the frequency of a gene variant (allele) in a population due to random sampling of organisms.
c)
the total number of genetic characteristics in the genetic makeup of a species.
d)
a significant number of individuals in a population die or are otherwise prevented from breeding.

Natural selection is:
a)
a significant number of individuals in a population die or are otherwise prevented from breeding.
