What do phylogenetic trees illustrate? These diagrams don't ... by invoking just four events of trait evolution. As this example illustrates, descendants of an ancestral lineage tend to share ...

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 ...
