5. A species that has a high rate of long-distance dispersal is more likely to colonize new habitat. But that species may also be less likely to adapt to local conditions, because migration will be stronger than local selection pressures for many loci. In light of those considerations, when do you expect that increasing dispersal might result in the evolution of a larger geographic range, and when might it not?

When migrating, the species must adapt to the new arrival sites and each place will have different conditions and special requirements to mate.

On the other hand, if the geographical area is the one that changes, the species will also undergo changes, when the species has long-distance migrations, the final result will not have significant variation, because there are no accumulations of place of variation, so when these changes occur evolution occurs and the most successful species have the best adaptations
