"I have found it difficult, when looking at any two species, to avoid picturing to myself, forms DIRECTLY intermediate between them. But this is a wholly false view; we should always look for forms intermediate between each species and a common but known progenitor; and the progenitor will generally have differed in some respects from all its modified descendants." Charles Darwin, Origin of Species 1st edition (on Kindle)
As Darwin admits, we should not two species and look at an intermediate as something that is some average of the two. So the ancestor of chimps and humans was not necessarily hairier than us but less hairy than chimps and with intermediate intelligence.
