1. The creation of phylogenetic trees from molecular data hasfacilitated the study of many questions in evolutionary biology.Describe one example of how having a phylogenetic tree has added toour understanding of either speciation or adaptation (note: forspeciation it is not sufficient to simply determine how species arerelated to each other). Be sure to compare how this question wouldbe studied in the absence of a robust phylogeny with what is gainedby having a phylogeny for the group.

Contrast theconsequences of current habitat fragmentation with the vicarianceevents that occurred during the Pleistocene
