How can migration lead to evolutionary change?


Open in App
Solution

Migration:

  1. The movement of individuals, groups, or populations from one place to another is termed migration.
  2. Migration causes the transfer of genes from one population to the other.
  3. Migration is also referred to as gene flow in which there is the transfer of genetic material.
  4. Even when there are no other evolutionary processes taking place, the process of gene flow can easily lead to evolution.
  5. The loss or gain of people in a population will certainly change the gene pool frequencies and thus leading to evolution.
