Web1.6 How Phylogenies are Made Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary … WebKathleen Fitzpatrick. Figure 26.1. Phylogeny is the evolutionary history of a species or group of related species. . The discipline of systematics classifies organisms and determines their evolutionary relationships. . Systematists use fossil, molecular, and genetic data to infer evolutionary relationships.
