Who is the Missing Link?

Answer 1

The specific "missing link" was a proposed extinct creature halfway in the evolutionary line between modern humans and their anthropoid progenitors, originally conceived as connecting humans to existing primate species. Since the actual evolutionary premise is that both apes and humans had a common ancestor (who may not have greatly resembled either of them), a "missing link" is highly unlikely to have existed at all.

* The fictional animated character Link in "Monsters vs. Aliens" (2009) is an ape-fish hybrid that does not correspond to the typical definition of the term.
