WebPhylogenies trace patterns of shared ancestry between lineages. Each lineage has a part of its history that is unique to it alone and parts that are shared with other lineages. Similarly, each lineage has ancestors that are unique to that lineage and ancestors that are shared with other lineages — common ancestors. WebA phylogenetic tree is a diagram that displays the evolutionary history of a group of organisms. The trees can represent relationships between any related groups, from all life on Earth to specific subspecies of algae. Phylogeny assumes that every organism shares a common ancestor and that all organisms fit in the tree of life.
