Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time?
1. Biogeographic isolation affects the random changes that take place within gene pools.
2. Biogeographic isolation causes changes in gene pools that result from
populations being separated.
3. Biogeographic isolation determines who will win competition for mates.
4. Biogeographic isolation determines the time that populations will breed.
