A phylogenetic tree is a graphic that shows how creatures have evolved over time. Phylogenetic trees are only that: theories, not facts. A phylogenetic tree's branching pattern indicates how species or other groupings emerged from a common ancestor. Two species are more linked in trees if they have a recent common ancestor, and less related if they share a distant common ancestor. Phylogenetic trees can be drawn in a variety of ways. The information carried by a tree does not change as it is rotated around its branch points. Get started with EdrawMax if you're seeking for a solution to organize and manage your workflows.
