WebA phylogenetic tree is a visual representation of the relationship between different organisms, showing the path through evolutionary time from a common ancestor to different descendants. Trees can represent relationships ranging from the entire history of life on earth, down to individuals in a population. WebIn a rooted tree, path from root to a node represents an evolutionary path. The root represents the common ancestor. Some trees do not have a well-defined common ancestor. We calls these unrooted trees . An unrooted tree specifies relationships among things, but not evolutionary paths. Constructing Phylogenetic Trees The basic task:
