Difference Between Monophyletic and vs Paraphyletic and
- A monophyletic group is a group of organisms that includes an ancestral species and all of its descendants. In other words, it is a group that has a single common ancestor and is considered a natural group or clade. This can be contrasted with a polyphyletic group, which includes organisms from multiple evolutionary lineages that do not share a com...
