Osborn (a colleague of Simpson at the American Museum during Simpson's early years) that long-term phenomena of evolution (macro evolution), such as speciation or major changes in a line of descent (for example, the shift from three-toed to one-toed horses), required explanations that could only be reached through studies of the fossil record. His dissertation concerned fossils in the Peabody Museum collection dating from the Mesozoic era, a period that marked the first appearance of mammals. Graduate work at Yale University culminated in a Ph.D. in Geology in 1926 with a thesis on Mesozoic mammals. Rensch, Bernard. In the preface to a 1984 reissue of Tempo and Mode, Simpson noted that the “punctuation,” or sudden appearance of new species, that is part of current “punctuated equilibrium” theory is essentially a restatement of “quantum evolution” first proposed in Tempo and Mode: “origin of a species or other taxon by exceptionally rapid evolution.”. his study of Mesozoic mammals—the oldest fossilized mammals, of which there was a rare collection in the Peabody Museum at Yale. Simpson collaborated with his wife, Anne Roe, on a classic 1939 book, Quantitative Zoology, that introduced statistical methods and population thinking to evolutionary disciplines that make little sense without them. He credited camping, mountain climbing, and mining with his father for inspiring an interest in geology. With Anne Roe and Richard C. Lewontin. It is interesting for the insight it gives of an exceptional scientist struggling to understand and explain himself. ."

However, upon reading the work of American paleontologist George Gaylord Simpson and initiating a correspondence with him, he instead decided to pursue his interest in evolution. He chose for the subject of his thesis the mammals of the Mesozoic Era, which are important for the understanding of mammalian evolution, although evidence of their existence consists mainly of tantalizing fragments of jaws and teeth. This resulted in a major work on the Paleocene fauna of the Fort Union Formation of Montana, in which about 50 mammals of a variety of primitive types were found. He was also a prolific writer who produced several important texts. The breadth of his studies of mammalian evolution led to the writing of a detailed classification of mammals that is standard in the field.
