Description: Emergence of Whales : Evolutionary Patterns in the Origin of Cetacea, Hardcover by Thewissen, J. G. M. (EDT), ISBN 0306458535, ISBN-13 9780306458538, Like New Used, Free shipping in the US A snapshot of the current explosion of research, spurred by the many fossil finds over the past two decades, into how four-footed land mammals evolved into whales, dolphins, and porpoises. The field is still new enough that much is yet unclear or controversial, so the 16 accounts present different views and theories of the available evidence. They include discussions of the middle to late Eocene Basilosaurines and Dorudontines, molecular evidence for the phylogenetic affinities of Cetacae, relationships of Cetacae to terrestrial ungulates and the evolution of cranial vasculature in Cete, the homology and transformation of Cetacean ectotympanic structures, implications of vertebral morphology for locomotor evolution in early Cetacae, structural adaptations of early Archaeocete long bones, the evolution of thermoregulatory function in the reproductive systems, isotropic approaches to the transition from land to sea, evolutionary turmoil during the invasion of the oceans, and other topics.
