Everybody likes popular science stories with clear and simple eureka moments. In the case of Charles Darwin’s theory of Evolution his voyage on board the H.M.S. Beagle and exploration of the Galapagos archipelago usually serves for such narrative purpose.

Of course Darwin’s story is much more complex, richer and interesting. Something seldom mentioned is Darwin the taxonomist. He published extensive monographs revising the classification of extant and extinct barnacles (Cirripedia). Taxonomic work at that scale amounted the study of morphology, ontogeny and biogeography across many species in a comparative framework. It does provides a great perspective that was an influential piece in Darwin’s synthesis.

It is with great pleasure then that I see that this week’s Science Magazine cover portraits plates of Darwin’s monographs for their special issue on speciation.
