DAVID: Still trying to decide on the last common ape/human ancestor, the shoulder anatomy gives clues:-http://phys.org/news/2015-09-shouldering-burden-evolution.html-QUOTE: "The results showed that australopiths were intermediate between African apes and humans: the A. afarensis shoulder was more like an African ape than a human, and A. sediba closer to human's than to an ape's. This positioning is consistent with evidence for increasingly sophisticated tool use in Australopithecus.
"'The mix of ape and human features observed in A. afarensis' shoulder support the notion that, while bipedal, the species engaged in tree climbing and wielded stone tools. This is a primate clearly on its way to becoming human," Alemseged said."
-I don't know if Tony is still logging on, but it was always the australopiths that I tried to draw attention to during our discussions: the creatures that are not recognizably ape or human. I think they are important evidence for evolution as opposed to separate creation.
