The changes without mutation would be limited, but a population can still evolve without mutations using:What mechanism allows for adaptation w/o a mutation?
- Natural selection is the process by which the best-adapted individuals produce the most offspring, which in turn carry forward to their offspring the genes that gave their parents the upper edge.
- Genetic drift is a random process in which chance plays a role in deciding which gene variants (alleles) survive.
- Gene flow occurs when genes are carried from one population to another. Also called migration, an example of gene is when pollen gets blown to a region where it previously did not exist, transporting new genetic material to that population.
So can evolution occur without mutations, yes . . . sort of.
