Definition

A similarity in the structure or function of parts or organs in different species that arises not from a common ancestor but from independent evolution, often due to similar environmental pressures.

Example

The wings of birds and bats are an example of homoplasy, as they evolved independently in different species.

Conversation

Have you ever heard about homoplasy in evolution?

Yeah, I think it refers to similarities that aren't from a common ancestor, right?

Exactly! It's fascinating how species can evolve similar traits independently.

It really shows how adaptable life can be in different environments.

Root Explanation

Homoplasy → It is formed from "homo-" (from Greek "homos", meaning same) and "plasy" (from Greek "plassein", meaning to form or shape). The term refers to a similarity in form or function that has evolved independently in different species, hence the idea of 'same shape' arising from different evolutionary paths.

Memory Tip

Think of 'same' ('homo-') and 'shape' ('plasy') to remember that homoplasy refers to similar forms that arise independently in different organisms.
