There are few creatures more beautiful, aloof, and fascinating than giraffes. Their social and ecological impact has been documented by many researchers. However, the inner workings of extant giraffes are less well known. That is why Graham Mitchell decided to write How Giraffes Work: a comprehensive overview of the anatomy, physiology, and biochemistry--in short, the normal functions--of a free-living, wild animal in its natural environment. A zoologist, veterinarian, and physiologist, Mitchell explains how giraffes get through their day. Additionally, he takes readers through the evolution of their physical characteristics, such as their size, shape, and coat markings. His approach integrates history with the physiology, anatomy, biochemistry, behavior, evolution, genetics, ecology, climate science, and more. Each chapter follows the discovery and utility of a different characteristic of giraffes. Illustrated with over two hundred figures and diagrams, the book explains how giraffes might have evolved and survived over many millions of years as well as how our perception of them has changed throughout history. So, how do giraffes work? The answers lie in a story filled not only with the details of their internal working but also with the labors of the extraordinary scientists who have put so many pieces of this puzzle together.
