Guy Coburn Robson (1888–1945) was a British zoologist, specializing in Mollusca, who first named and described Mesonychoteuthis hamiltoni, the colossal squid.
Robson studied at the marine biological station in Naples, and joined the staff of the Natural History Museum in 1911, becoming Deputy Keeper of the Zoology Department from 1931 to 1936.
Robson is best known for his major book The Variations of Animals in Nature (co-authored with O. W. Richards, 1936) which argued that although the fact of evolution is well established, the mechanisms are largely hypothetical and undemonstrated.
[1][2] Zoologist Mark Ridley has noted that "Robson and Richards suggested that the differences between species are non-adaptive and have nothing to do with natural selection.
"[5] The following marine species have been named after Guy Robson to honour his contribution to science:[6] "In short, we do not believe that Natural Selection can be disregarded as a possible factor in evolution.
