" "Humans are not apes" when we clearly are. Its hard for people to accept the fact that chimps are almost human.(and Humans are almosts chimps). Some reason humans think very highly of our species"
I think this point cannot be made strong enough. One example I like to make is from Johanson & Edey's "Lucy". In that book there is a chapter which describes Johanson and White's Plattian methodology for naming their new species (my term, not theirs). As a quick aside, for those not familiar with Platt, I offer a short explanantion. Platt (1964) outlined a method of scientific reasoning called "strong inference." You address a scientific question by describing all possible hypotheses and designing experiments to eliminate all of the them. The hypothesis that cannot be disproven stands as your strongest.
Johanson and White start their analysis by describing all possible taxonomic categories that their new species may fit. They come down to three; Australopithecus, Homo, and something new. They then describe the methodology they use to categorize the species into the genus Australopithecus. All in all, an excellent analysis. BUT the question I had is why was Pan not included? I am not saying it should have been chosen, but in Plattian methodology you include all likely possibilities.
Throughout the book (and the associated papers) Australopithecus afarensis is repeatedly called "chimpanzee-like" in multiple skull characteristics. I would think that this comparison would at least invite the consideration that the new species might fit this genus. But is was never considered. I argue that this is because what they had was a human, however primitive, and not an ape (semantics) so that an ape genus could not be considered.
I think it was Roger Lewin who coined the term "pithecophobia" for paleoanthropologists who want to push apes as far away from human evolution as possible. I think I am in Jared Dimond's "third chimpanzee" camp. I think if we were an alien race of taxonomists studying the apes of Africa we would clearly categorize a chimpanzee clade spit into bipedal forms and non-bipedal forms. Again the opinion of an invertebrate zoologist who thinks all vertebrates look alike anyhow.
