Nature's Giants: The Biology and Evolution of the World's Largest Lifeforms

The past and present giants of our world--dinosaurs, whales, and even trees--are a source of unending fascination, and their sheer scale is awe-inspiring. Size is integral to the way that organisms experience the world: a puddle that a human being would step over without thinking is an entire world to thousands of microscopic rotifers. But why are creatures the size that they are? Why aren't bugs the size of elephants, or whales the size of goldfish?

In this beautifully illustrated new book, biologist Graeme Ruxton explains how and why nature's giants came to be so large, for example, how decreased oxygen levels limited the size of insects and how island isolation allowed small-bodied animals to evolve larger body sizes. Through a diverse array of examples, from huge butterflies to giant squid, Ruxton explores the physics, biology, and evolutionary drivers behind organism size, showing what it's like to live large.
