Then in 1987 he published a book titled The Red Ape: Orang-utans and Human Origins, which presents the idea at much greater (sometimes tedious) length.
Was the out-of-Africa hypothesis established by this point? How does his timeline/phylogeny fit in with other branches of human evolution? He says molecular evidence is inconclusive, but wouldn't anatomical evidence be more so? Form follows function. I've heard of convergent evolution, but doesn't that more readily apply to anatomy than chemistry?
Update: yeah, google says Orangs branched off way earlier than gorillas and chimps. The prevailing theory is not always the right one, but in this case current science confirms earlier beliefs.
