Title: Web Tutorial 29.1 Plant Evolution and the Phylogenetic Tree
Caption: A phylogenetic tree is a diagram that represents the evolutionary history of a group of organisms. Biologists construct such a diagram by analyzing fossils and by comparing the molecular and morphological characters of organisms. This tutorial examines how a phylogenetic tree for green plants reveals the relatedness of groups of plants and algae.
