"It is obvious from the above data that Natural Selection could have played no part in the development of Merychippus and that the causes of speciation are to be found within the animals themselves." (1942)
Second-rank American mammal paleontologist. White apparently worked under Barbour at Harvard. White worked at Thomas Farm during World War II, and in 1947 and 1948 collected Eocene and Oligocene mammals in the Wind River Basin in Wyoming and the Canyon Ferry Reservoir area in Montana. A "splitter," White often recognized multiple closely related species in the same fossil quarries, which later workers treated as identical. In his 1954 paper White, responding to Matthew's 1930 attack on splitting, defended this approach by citing obvious cases of species in the same genus that have overlapping geographic ranges. From 1958 through 1973 White published on dinosaurs, including material from Dinosaur National Monument. White's orthogenetic views, as expressed in the above quote, were fairly typical of American paleontologists in the 1930s and resembled Osborn's.
