5 B. Classifying Organisms Most of the organisms you see in lab will bear morphological features that help you to group them according to their relationships with other similar organisms. Although this type of evidence is often a reliable indicator, there may be other important lines of evidence that are ‘invisible’ when looking at an organism. Modern day taxonomists rely on evidence of evolution to arrange organisms into groups. List the four major types of evidence (including the two types of homology), from Chapter 22 (pp. 448-451) of Campbell and Reece (2005): 1. 2. 3. 4. These types of evidence all reflect divergent evolution - increasing dissimilarity between two or more populations that were initially one. Mutations and recombination are the sources of new phenotypes in individuals, which are then maintained or eliminated by natural selection. Before looking at the demonstrations for this section, we need to explain some terms that pop up frequently in discussions of evolution and taxonomy:
