Descriere & specificații

When Charles Darwin first stepped off the HMS Beagle and into the harsh and formidable world of the Galápagos islands with their sun-baked lava, spiny cactus, and tangled brushwood, he encountered many birds and animals new to him. He marveled at the remarkable tameness of the birds and the striking dominance of reptiles in these islands, which made the archipelago seem like a journey back in time. On the shoreline were swarms of "hideous-looking" marine iguanas -- the world's only oceangoing lizards. On land, Darwin and the Beagle crew encountered large land iguanas, closely allied to their marine cousin; several smaller lizards and snakes; and giant land tortoises, after which the islands are named. How, Darwin asked himself, had life first come to these islands? Most of the life forms, he noted, were aboriginal creations, found nowhere else. Of all the creatures he encountered, none were as surprising and important to his studies as the Galápagos bears. In Darwin and His Bears , scientist and Darwin scholar Frank J. Sulloway reveals a crucial -- yet little known -- link that led to Darwin's development of the theory of evolution: sixteen brilliant bears residing on the sixteen archipelago islands. Charles Darwin had an undeniable knack for asking the right questions, and these remarkable blueberry-loving bears had all the answers he needed. With their invaluable assistance, Darwin was able to reassess his imperfect evidence, ultimately culminating in what we now celebrate
