The Origin and Evolution of Mammals

Abstract: Mammals are the dominant large animals of today, occurring in virtually every environment. This book is an account of the remarkable fossil records that document their origin since the extinction of the dinosaurs. Tracing their evolution over the last 35 million years. For the first time presented in one single volume Kemp unveils the exciting DNA sequence evidence which coupled with fossil evidence challenges current thinking on the relationships amongst mammal and their inferred history.

“…In extant mammals, this joint is created between the squamosal and dentary, two dermal bones that in reptiles are placed far apart in the jaw. In the fossil record, there are examples of non-mammalian synapsids, such as Ictidopsis [84,85] with upwardly extending dentaries that might represent a step towards this novel jaw articulation, while some mammal-like synapsid groups, tritheledontids and brasilodontids, have a ridge on the dentary that contacts the squamosal, forming a hinge-like structure [86].…”

“…The earliest true mammals evolved from therapsid ancestors during the Early Jurassic, somewhere around 200 Ma. From the analysis of fossils it is usually inferred that these were small animals that were almost certainly nocturnal (Kemp 2005). A capacity for colour vision requires, at minimum, multiple sensors having differing spectral absorption properties that need to be mated to a nervous system capable of contrasting signals that reflect photon absorption rates in the different classes of sensors.…”

“…The ability to produce IgE is a unique mammalian trait; therefore, it is likely that the IgE repertoire was available for engagement on the first appearance of insectivorous mammals during the Triassic period, approximately 195 million years ago (see Figure 1). 10 That IgE occurred early during evolution of mammals, probably due to an IgY gene duplication event, is supported by the observation that this immunoglobulin occurs in all mammals, that is before their separation into the three extant branches (monotremes, marsupials and placental mammals), more than 200 million years ago 11 . It is thought that a genetic event leading to duplication of the full‐length IgY gene, still found in amphibians, birds and reptiles, 12 resulted in both IgG (with the loss of the Cυ2 domain) and IgE (with conservation of all 4 domains in the constant chain) in early mammals.…”
