Root Explanation

Anagenesis is formed from "ana-" (meaning up or back) and "genesis" (from Greek "genesis", meaning origin or creation). The term describes a process of evolution where a species evolves into a new form without branching into separate lineages, thus representing a return to an earlier state or a new beginning.

Memory Tip

Think of 'up' or 'back' ('ana-') leading to a 'new origin' ('genesis') — this helps you remember that anagenesis refers to a process of evolution that leads to a new form.
