Suppose a small group of individuals migrates and colonizes in a new area away from the original range of the species. The area inhabited by these migrants becomes geographically isolated from the original population and this new population eventually evolves into a new species. Which of the following processes would NOT contribute to the two populations diverging genetically?
- different selection pressures
- gene flow between the new and original population
- founder effect
- different mutations arising in each population
