Root Explanation

Monophyly → It is formed from "mono-" (meaning single or one) and "phylon" (from Greek, meaning tribe or race). The term refers to a group of organisms that are descended from a common ancestor, thus representing a single lineage.

Memory Tip

Think of 'mono-' meaning 'one' and 'phylon' meaning 'tribe' — this helps you remember that monophyly refers to a single lineage of organisms.
