3.8M-year-old skull of an early ape-like human ancestor discovered in Ethiopia
Why does it have to be only one ancestor ape, and not several that evolved human-like features simultaneously in the same environment?<p>We have Neanderthal DNA, that we inherited through interbreeding.<p>Why can't both we and the Neanderthals be descendent from a varied group of very similar apes that interbred as well? Isn't this the most likely scenario?<p>Sometimes I think scientists fall for the same simplistic patterns of thinking that the men on the street fall for every day.<p>Like, there is only one solution, there is only one cause, there is only one reason, when in fact reality is much more complex than that.
