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?

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
