     Fifty Animals that Changed the Course of History is a beautifully presented guide to the animals that have had the greatest impact on human civilization. Entries are organized by scientific name, except for Homo sapiens, which is featured last.The 50 animals include the horse, dog, rat, whale, reindeer, beaver, flea, leech, dodo, falcon, oyster and shark. These creatures, great and small, have played central roles in the evolution of humankind, but they have remained at the periphery of our understanding of history. Whether it is an advancement in scientific knowledge, a trade war, disease and death, battles won and lost, or encounters with explorers in unknown lands, these animals have changed the course of history.More than 150 elegant drawings, photographs and paintings, as well as excerpts from literature, highlight the concise text. Each animal is judged by its influence in four categories: Edible -- animals that have shaped agriculture, such as the cow Medical -- animals that are "disease vectors," spreading bacteria and viruses, from malaria to plague Commercial -- animals used for trade or in manufacturing Practical -- animals used for transportation or clothing. The animals described in Fifty Animals that Changed the Course of History are familiar, but their roles in human history are easily overlooked. This attractive reference gives us a fresh perspective on our place in the animal kingdom.

    Honey bees, and the daily workings of their close-knit colonies, are one of nature's great miracles. And they produce one of nature's greatest edible bounties: honey. More than just a palate pleaser, honey was once an offering to the gods, a preservative, and a medicine whose sought-after curative powers were detailed in ancient texts . . . and are being rediscovered by modern medical science.In Letters from the Hive, Prof. Stephen Buchmann takes us into the hive--nursery, honey factory, queen's inner sanctum--and out to the world of backyard gardens, open fields, and deserts in full bloom, where the age-old sexual dance between flowers and bees makes life on earth as we know it possible. Hailed for their hard work, harmonious society, and, mistakenly, for their celibacy, bees have a link to our species that goes beyond biology. In Letters from the Hive, Buchmann explores the fascinating role of bees in human culture and mythology, following the "honey hunters" of native cultures in Malaysia, the Himalayas, and the Australian Outback as they risk life and limb to locate a treasure as valuable as any gold.To contemplate a world without bees is to imagine a desolate place, culturally and biologically, and Buchmann shows how with each acre of land sacrificed to plow, parking lot, or shopping mall, we inch closer to what could become a chilling reality. He also offers honey-based recipes, cooking tips, and home remedies--further evidence of the gifts these creatures have bestowed on us.Told with wit, wisdom, and affection, and rich with anecdote and science, Letters from the Hive is nature writing at its best. This is natural history to be treasured, a sweet tribute that buzzes with life.From the Hardcover edition.
