Root Explanation

Monophyletic → It is formed from "mono-" (meaning single or one) and "phyletic" (from Greek "phyle", meaning tribe or race). The word describes a group of organisms that are derived from a single common ancestor, hence a single lineage.

Memory Tip

Think of 'mono-' meaning 'one' and 'phyletic' relating to a 'tribe' or 'lineage' — this helps you remember that monophyletic refers to a group coming from one common ancestor.
