The Nervous System of the Tupaiidae: Its Bearing on Phyletic Relationshipss primates by many authorities (e. g. Simpson, 1945). Their current popularity as experimental subjects in neuroanatomy and neurophysiology has been a direct outgrowth of that status. Now that the view that they are primitive primates is less widely held, other considerations are being used to ratio

The Use of Reproductive and Developmental Features in Assessing Tupaiid Affinitiesf extant tree shrews which might provide insight into their evolutionary relationships with primates or other eutherians. Reproductive features were among the earliest to be cited as evidence of a special tupaiid-primate relationship. Kaudern (1911) was one of the first investigators to suggest clos
