Evolutionist and Missionary, John Thomas Gulick: Portrayed through Documents and Discussions

Nature volume 131, page 532 (15 April 1933) | Download Citation



THE Rev. J. T. Gulick, who died in 1923, was an American missionary who will be remembered for his researches on the land-shells of the Sandwich Islands. He made a large collection, and observed that there were numerous species and varieties of each genus, which were restricted not merely to the same island, but even to the same valley. He thus elaborated a theory of divergent evolution by isolation, which he discussed in papers to the Linnean Society of London and in four letters to NATURE. On this subject he corresponded with A. R. Wallace, and especially with G. J. Romanes, who gave Gulick's work a prominent place in the third volume of his “Darwin, and after Darwin”(1897).
