Have you ever heard of the term vicariance?

Yeah, I think it has to do with how species evolve when separated, right?

Root Explanation

Vicariance → It is formed from "vicis" (meaning change or alternation) and the suffix "-ance" (indicating a state or quality). The word describes the state of being changed or altered, particularly in the context of biogeography where it refers to the separation of species due to geographical barriers.

Memory Tip

Think of 'change' ('vicis') to remember that 'vicariance' refers to the state of being changed, especially in how species are separated by geographical barriers.
