Thus, just as a kind of population thinking is required to appreciate the evolutionary significance of variation among individuals, a kind of tree thinking is required to appreciate the evolutionary significance of the history of ancestor-descendant relationships that unites all levels of organization: genes, individuals, populations, species, higher taxa. What are the goals of modern systematics? 1. Differentiate individual organisms and establish the basic units: species 2. to arrange these units in a logical hierarchy that permits easy and simple recognition in the basis of similarity = classification 3. to keep the details of 1 and 2 separate = nomenclature 4. determine the evolutionary (ancestor-descendant) relationships between all levels of the hierarchy = phylogeny ....
