Abstract

Modern views on the origin and early evolution of mammals are presented. The work uses the material accumulated by the author on the morphology of modern and fossil monotremes, marsupials and placentals. Data on Mesozoic mammals, including those obtained in recent years, are summarized. A model of the mechanism of morphogenetic transformations during the evolutionary development of Mammalia is proposed. An overview of the main directions of the formation of mammals from the Late Triassic to the Cenozoic is given.
