Island Biogeography and Evolution: Solving a Phylogenetic Puzzle With Molecular Genetics
In this lesson students use real data to develop likely phylogenies for seven related populations of lizards living on the Canary Islands (off the west coast of Africa). Three phylogenetic charts will be constructed, each using different forms of data: geography, geology, morphology, and molecular genetics (DNA comparisons). The lesson serves as an example of MILE: Multiple Independent Line of Evidence, showing at least some degree of similarity of patterns and therefore mutual confirmation of the phylogeny.
