A supposed animal midway in evolution between apes and humans. The term is based on a misunderstanding about the theory of evolution, which does not state that humans are descended from apes, but rather maintains that both humans and apes descended from a common ancestor. Modern evolutionary scientists do not search for a “missing link.”
hypothetical extinct creature halfway in the evolutionary line between modern human beings and their anthropoid progenitors. In the latter half of the 19th century, a common misinterpretation of Charles Darwin's work was that humans were lineally descended from existing species of apes. To accept this theory and reconcile it with the hierarchical Great Chain of Being, some fossil ape-man or man-ape seemed necessary in order to complete the chain. Today it is recognized that the relationship of modern humans to the present anthropoid apes (e.g., chimpanzees) is through common ancestors rather than through direct descent. These ancestors have yet to be identified, but ape-hominid divergence may have occurred 6 to 10 million years ago.
