What Is Phylogeny?. Phylogeny is the study of relationships among different groups of organisms and their evolutionary development. Phylogeny attempts to trace the evolutionary history of all life on the planet. It is based on the phylogenetic hypothesis that all living organisms share a common ancestry. The relationships among organisms are depicted in what is known as a phylogenetic tree. Relationships are determined by shared characteristics, as indicated through the comparison of genetic and anatomical similarities.. BIG IDEA I:. THE PROCESS OF EVOLUTION EXPLAINS THE DIVERSITY AND UNITY OF LIFE.. Connecting evolutionary changes in a population over time to change(s) in the environment by describing these examples:.
