A phylogenetic tree, also called and evolutionary tree, is a tree showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor of the descendants, and the edge lengths in some tree correspond to time estimates.
A clade is a piece of a phylogeny that includes an ancestral lineage and all the descendants of that ancestor. This group of organisms has the property of monophyly (from the Greek for single clan), so it may also be referred to as a monophyletic group. phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
