Abstract
Phylogeny defined as the context of evolutionary biology is the connections between all groups of organisms as understood by ancestor/descendant relationships. Since many groups of organisms are now extinct, we can’t have as clear a picture of how modern life is interrelated without their fossils. Phylogenetics, the science of phylogeny, is a useful tool severed as one part of the larger field of systematic including taxonomy which is a practice and science of naming and classifying the diversity of organisms.
