In not a chimp I resoundingly make the point that the differences between humans and chimps are more likely to be found in the crucial differences in gene expression between the two species rather than evolved sequence changes in genes per se. This paper, who's authors read like a who's who of human-chimp comparative biology - has just underlined this point very clearly by showing that gene expression is fairly similar over a range of metabolic processes, but in the brain, especially the caudate nucleus and the anterior cingulate cortex, they diverge dramatically, revealing "significant differences in neuronal communication, ion transport, and regulatory processes, whereas protein comparisons indicated differences in perception and cognition, metabolic processes, and organization of the cytoskeleton." The link above is to the full paper which is open access.
