John Thomas Gulick (March 13, 1832 – April 14, 1923) was an American missionary and naturalist from Hawaii. He was one of the pioneers of modern evolutionary thinking based on his studies of Hawaiian snails of the genus Achatinella. He was among the first to describe the formation of species through geographic separation of breeding populations. He developed early ideas on the founder effect and what is now known as the Baldwin effect. He coined the term "divergent evolution".[1]
