About this product
- DescriptionIn the geological blink of an eye, mammals moved from an obscure group of vertebrates into a class of planetary dominance. Why? J. David Archibald's provocative study identifies the fall of disaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. Archibald refutes the widely accepted single-cause impact theory for disaur extinction. He demonstrates that multiple factors-massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact-likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial disaurs did t. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following navian disaur extinction. Archibald argues that because of disaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cezoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cezoic mammals evolved into the forms we recognize today in a mere ten million years after disaur extinction. Extinction and Radiation is the first book to convincingly link the rise of mammals with the fall of disaurs. Piecing together evidence from both molecular biology and the fossil record, Archibald shows how science is edging closer to understanding exactly what happened during the mass extinctions near the K/T boundary and the radiation that followed.
