This diagram is an example of a simple phylogenetic tree. In most cases, researchers draw phylogenetic trees in such a way as to record only those events that are relevant to a set of living taxa.

Consider the great ape example I worked through with an Excel spreadsheet (link above). These are Jukes-Cantor distances based on number of mtDNA sequence differences. [See Glossary and pp. 91-93 of ...

In biology, phylogenetic trees represent the evolutionary history and diversification of species -- the "family tree" of Life. Phylogenetic trees not only describe the evolution of a group of ...
