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.
2. One consequence of an expanding human population is thefragmentation of other species ranges. Describe the majorconsequences of habitat fragmentation in terms of populationgenetic variation and extinction probability. Contrast theconsequences of current habitat fragmentation with the vicarianceevents that occurred during the Pleistocene
