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.
Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

In the pages that follow, the story of commercial whaling in the western Arctic is told by a scholar intimately acquainted with the terrain--not only as it can be found in the historical records or at archaeological sites, but from lone experience on the shores and waters where the great adventure was played out. His book is written with such mastery and vigor that we confidently greet it as the finest history yet written on any aspect of American whaling.
Genomic science indicates that humans descend not from an individual pair but from a large population. What does this mean for the basic claim of many Christians: that humans descend from Adam and Eve? Leading evangelical geneticist Dennis Venema and popular New Testament scholar Scot McKnight combine their expertise to offer informed guidance and answers to questions pertaining to evolution, genomic science, and the historical Adam. Some of the questions they explore include: - Is there credible evidence for evolution? - Do we descend from a population or are we the offspring of Adam and Eve? - Does taking the Bible seriously mean rejecting recent genomic science? - How do Genesis's creation stories reflect their ancient Near Eastern context, and how did Judaism understand the Adam and Eve of Genesis? - Doesn't Paul's use of Adam in the New Testament prove that Adam was a historical individual? The authors address up-to-date genomics data with expert commentary from both genetic and theological perspectives, showing that genome research and Scripture are not irreconcilable. Foreword by Tremper Longman III and afterword by Daniel Harrell.
Drawing on their own research as well as scientific literature including evolutionary biology, animal behavior, ecology, anthropology, psychology and neuroscience, two cetacean biologists submerge themselves in the unique environment in which whales and dolphins live. --Publisher's description.
“A palaeontological howdunnit…[Spying on Whales] captures the excitement of…seeking answers to deep questions in cetacean science.” —Nature Called “the best of science writing” (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales, from their four-legged past to their perilous present. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still so much we don't know about them. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea--and what can their lives tell us about evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive? Nick Pyenson's research has given us the answers to some of our biggest questions about whales. He takes us deep inside the Smithsonian's unparalleled fossil collections, to frigid Antarctic waters, and to the arid desert in Chile, where scientists race against time to document the largest fossil whale site ever found. Full of rich storytelling and scientific discovery, Spying on Whales spans the ancient past to an uncertain future--all to better understand the most enigmatic creatures on Earth.
With their haunting ocean "songs" and gushing spouts, whales great or small inspire awe. Though their impressive size and might protect them from most natural dangers, intensive hunting by humans has put them right at the top of the conservation agenda. This wonderfully illustrated guide covers classification of all the whale families: blue whales (the world's largest mammals), magnificent humpbacks, sperm whales, and right whales, as well as dolphins and other cetaceans. A uniquely informed text written by a world expert accompanies a wide range of photographs and illustrations of whales leaping, blowing, and swimming. Realistically examine the implications of the commercial exploitation of whales and dolphins. Dramatic stories of whale hunts from the past give the history behind the present-day problems. Information on the dolphin's high intelligence and gentleness make these playful beings all the more endearing. You'll see clearly why they deserve our protection and respect!
