I'm an African-American, and I find the objections to the illustration completely over-the-top.   The illustration accurately depicts the characteristics of the classic  not universal  "Negroid" phenotype.  Dolichocephalic skulls are a classic feature of the Africoid phenotype.   

 Are there similarities between the skulls of the classic Africoid/Negroid phenotype and certain simians/primates?  Insofar as, in some instances, a pronounced prognathism and a dolichocephalic skull  yes, absolutely.  And the same can be said of flattened, rounded European skulls with regard to other simian/primate species.  So what?  The fact that such similarities in the case of Africoid populations have been used in the past to dehumanize and slander black folks has nothing to do with objective observation.  The fact is the illustration is dead-on accurate  not as a representation of all Africoid populations  but as an illustration of the phenotypical features which most distinctively differentiate fundamentally unmiscegenated Africoid populations from other human populations. 

 The only Caucasians (other than the East Indian Veddoid group, which incorrectly and calculatingly has been classified as "Caucasian", though they're as black Africoid as the Australoids and Nilotics) known as a group to have dolichocephalic skulls are Nordics.  The classic Caucasian skull would not apply to them, either; but taken collectively and regarded generally, the phenotype of the classic Caucasian skull is as accurate, generally, as its Africoid counterpart.  Maxillary and alveolar prognathisms are also classic features of the Africoid phenotype, a feature which often results in a receding chin line.  These collection of classic Africoid features is precisely the same set of characteristics which clearly reveal the mummy of King Tutankhamen as black African, rather than "Caucasoid North African," as was recently claimed in the shameful (and ongoing) whitewashing of ancient dynastic Egypt by Zawas and the usual lying, racist European suspects.  

 IMO, black folks need to get real and stop being so damned sensitive and reactionary.  F*** the racists and deal with the facts.  We can't on one hand use the phenotypical model to identify long-dead black African kings and then repudiate their fundamental accuracy and cry "racism" on another.
