Branching diagrams used to illustrate evolutionary relationships are called?

Branching diagrams that show how species are related through ancestry are phylogenetic trees. They place species at the ends of branches and connect them at branch points to represent common ancestors. The closer two species are on the tree, the more recent their shared ancestor, which helps illustrate evolutionary history and patterns of relatedness. This differs from ecology, which studies how organisms interact with their environments; population ecology, which looks at how populations change over time; and endemic, which describes a species that is native to a particular place. Even if you see the term spelled as “phylogenic,” the intended idea is the same—an evolutionary tree that maps relationships.
