Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galápagos finches first made famous by Charles Darwin. In How and Why Species Multiply, they offered a complete evolutionary history of Darwin's finches since their origin almost three million years ago. Now, in their richly illustrated new book, 40 Years of Evolution, the authors turn their attention to events taking place on a contemporary scale. By continuously tracking finch populations over a period of four decades, they uncover the causes and consequences of significant events leading to evolutionary changes in species. The authors used a vast and unparalleled range of ecological, behavioral, and genetic data--including song recordings, DNA analyses, and feeding and breeding behavior--to measure changes in finch populations on the small island of Daphne Major in the Galápagos archipelago. They find that natural selection happens repeatedly, that finches hybridize and exchange genes rarely, and that they compete for scarce food in times of drought, with the remarkable result that the finch populations today differ significantly in average beak size and shape from those of forty years ago. The authors' most spectacular discovery is the initiation and establishment of a new lineage that now behaves as a new species, differing from others in size, song, and other characteristics. The authors emphasize the immeasurable value of continuous long-term studies of natural populations and of critical opportunities for detecting and understanding rare but significant events. By following the fates of finches for several generations, 40 Years of Evolution offers unparalleled insights into ecological and evolutionary changes in natural environments.

Mankind may be on the brink of extinction. This story begins with a family living in an underground bunker in the year 2052, while the world above is in total chaos. Nicholas and his family escaped their home in Denver and are now in New Mexico trying to survive an apocalyptic event caused by an approaching comet. The earth has been subject to natural and man-made disasters never before experienced by man. In the bunker, Nicholas reflects back on the past forty years of his life. He remembers the joyful times and the tragic events that changed everything. He relives the taking down of America by terrorist groups, the battle of Armageddon in the Middle East, natural disasters caused by great earthquakes and asteroids that changed the landscape around the world, and the great plague that killed a third of the world's population. In this doomsday scenario, 2052 Prophecies: The Last 40 Years puts readers in the bunker alongside Nicholas and his terrified family huddled together as the earth shakes violently from the comet's approach. Is it in the Prophecies that mankind will survive? Originally from Massachusetts,

For millennia, we lived in harmony with the Earth, taking only what we required to survive. But in just the past few centuries, we have used our powers to satisfy our obsession with consumption and new technology, without regard for the consequences. And in doing so, we have exploited our surroundings on an unprecedented scale. In this revised and updated edition of From Naked Ape to Superspecies, David Suzuki and Holly Dressel lucidly describe how we have evolved beyond our needs, trampling other species, believing that we can make the Earth work the way we want it to. And they introduce us to the people who are fighting back, those who are resisting the inexorable advance of the "global economy" juggernaut, the people whose voices are difficult to hear over the din of corporate public relations machines. We learn about how human arrogance—demonstrated by our disregard for the small and microscopic species that constitute the Earth’s engine and our reckless use of technological inventions like powerful herbicides or genetically engineered crops—is threatening the health of our children and the safety of our food supply.

Presenting acclaimed essays from one of contemporary science fiction's most imaginative wordsmiths, this collection shows that Robert Silverberg's nonfiction is as witty and original as his fiction and full of acute observations and matter-of-fact insights. Whether he is discussing science fiction, history, cultural effects, science, or writing, Silverberg is always exploring new territories. As in his fiction, no cultural icon escapes his scrutiny, including fellow writers such as Robert Heinlein, Arthur C. Clarke, H. P. Lovecraft, and Isaac Asimov. Delightfully wicked commentaries on the concepts of thoughtcrimes, space exploration, the ancient Antikythera Computer, and the universal translator in science fiction fill these essays, many of which were originally published as columns in Asimov Science Fiction magazine.
