the combination of the theory of evolution and Linnaean taxonomy. - ANSWER✔✔-a unified theory of
evolution that combines genetics with natural selection.
Thomas Malthus's contribution to natural selection is the:
a. binomial taxonomic system of naming species.
b. theory that the earth's old age is based on geologic evidence resulting from cataclysmic
events.
c. observation that an abundance of food would allow a population to increase geometrically
and indefinitely, but there simply is not enough food, so populations are limited by food
supply.
d. theory that environmental resources increase to population pressures. - ANSWER✔✔-c. observation
that an abundance of food would allow a population to increase geometrically
and indefinitely, but there simply is not enough food, so populations are limited by food
supply.
Darwinian evolution proposes that:
a. species adapt and change over time based on the environment.
