Phylogenetic (evolutionary) Tree • showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor. • Each node is called a taxonomic unit. • Internal nodes are generally called hypothetical taxonomic units • In a phylogenetic tree…

A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. phylogenetic trees Strains that are phylogenetically closer are . more likely .

Phylogenetic trees represent hypotheses about the evolution of life. They are only as good as the data on which they are based. The data come from our studies of modern organisms and fossils. We do no know everything about modern organisms, and the fossil record includes very few of the organisms that actually lived.
