Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Picture a world of dog-sized scorpions and millipedes as long as a car; tropical rainforests with trees towering over 150 feet into the sky and a giant polar continent five times larger than Antarctica. That world was not imaginary; it was the earth more than 300 million years ago in the Carboniferous period of the Paleozoic era. In Carboniferous Giants and Mass Extinction, George R. McGhee Jr. explores that ancient world, explaining its origins; its downfall in the end-Permian mass extinction, the greatest biodiversity crisis to occur since the evolution of animal life on Earth; and how its legacies still affect us today. McGhee investigates the consequences of the Late Paleozoic ice age in this comprehensive portrait of the effects of ancient climate change on global ecology. Carboniferous Giants and Mass Extinction examines the climatic conditions that allowed for the evolution of gigantic animals and the formation of the largest tropical rainforests ever to exist, which in time turned into the coal that made the industrial revolution possible—and fuels the engine of contemporary anthropogenic climate change. Exploring the strange and fascinating flora and fauna of the Late Paleozoic ice age world, McGhee focuses his analysis on the forces that brought this world to an abrupt and violent end. Synthesizing decades of research and new discoveries, this comprehensive book provides a wealth of insights into past and present extinction events and climate change.

From humans to hermit crabs to deep water plankton, all living things compete for locally limiting resources. This universal truth unites three bodies of thought--economics, evolution, and history--that have developed largely in mutual isolation. Here, Geerat Vermeij undertakes a groundbreaking and provocative exploration of the facts and theories of biology, economics, and geology to show how processes common to all economic systems--competition, cooperation, adaptation, and feedback--govern evolution as surely as they do the human economy, and how historical patterns in both human and nonhuman evolution follow from this principle. Using a wealth of examples of evolutionary innovations, Vermeij argues that evolution and economics are one. Powerful consumers and producers exercise disproportionate controls on the characteristics, activities, and distribution of all life forms. Competition-driven demand by consumers, when coupled with supply-side conditions permitting economic growth, leads to adaptation and escalation among organisms. Although disruptions in production halt or reverse these processes temporarily, they amplify escalation in the long run to produce trends in all economic systems toward greater power, higher production rates, and a wider reach for economic systems and their strongest members. Despite our unprecedented power to shape our surroundings, we humans are subject to all the economic principles and historical trends that emerged at life's origin more than 3 billion years ago. Engagingly written, brilliantly argued, and sweeping in scope, Nature: An Economic History shows that the human institutions most likely to preserve opportunity and adaptability are, after all, built like successful living things.

Artiodactyls are diverse and successful hoofed mammals, represented by nearly two hundred living species of pigs, peccaries, hippos, camels, deer, sheep, cattle, giraffes, and other even-toed ungulates. In the recent years, a tremendous amount of research has been conducted on this important order. The Evolution of Artiodactyls synthesizes this research into a single volume. The authors explore a variety of topics, including molecular phylogeny of terrestrial artiodactyls phylogenetic relationships of cetaceans to terrestrial artiodactyls, and the earliest artiodactyls—Diacodexidae, Dichobunidae, Homacodontidae, Leptochoeridae, and Raoellidae.
