Common descent

From EvoWiki

(Redirected from Common Descent)
Jump to: navigation, search

Common descent is the idea that two populations or species share a common ancestral species, and are both descended from that ancestor by normal processes of replication. This is a fairly commonplace notion.

The theory of common descent states that all species (on Earth, at least) share common ancestors, back to a single common ancestor of all life. This is a fairly profound notion.

The mechanisms that produce diversity from common ancestors are those of the Theory of Evolution. The word evolution is often confused with common descent.
