e. Australopithecus Afarensis "LUCY" -- Discovered in 1974 by Donald Johanson was a half complete skeleton he named after the Beetle's song "Lucy in the Sky With Diamonds". A year later 13 more similar skeletons were found. Remarkably the skull was even more ape-like than other australopithecenes.
In his book "Lucy, The beginnings of Human Kind," Johanson said: I had no problem with Lucy. She was so odd that there was no question about her not being human. She simply wasn't. She was too little. Her brain was way too small and her jaw was the wrong shape. Her teeth pointed away from the human condition and back in the direction of apes. The jaws had the same primitive features."
              On the basis of a hip and knee joint found later, however, Johanson "decided" that Lucy did walk in an upright bipedal fashion. He thus deduced Lucy was an ancestor of man, as well as an ancestor of A. africanus (the original Australopithecus).  Great science at work here.
