Very small amounts of DNA differences are required for HUGE differences in phenotypes. Great talk. I think it's plausible if the population of hominids was so small and confined to a lake or small peninsula. We'd also have to agree on a monogenesis theory (1 line as opposed to many differing lines)... Thanks for posting this.
quite interesting. It could also explain the missing link, because when they died they got chucked in the water (actually that sounds ridiculous, but whatever).
