Just the Right Size: Why Big Animals Are Big and Little Animals Are Little

by Nicola Davies

illustrations by Neal Layton

ISBN: 9780763639242

Why aren't insects the size of dogs? Why are ants stronger than humans? Why couldn't Superman really exist? It all comes down to a rule of geometry: "If you double the length of something, its surface area and cross section go up four times, while its volume and weight go up eight times!" Fascinating examples and funny illustrations demonstrate how this rule governs the size of every creature on Earth. Index. Glossary. Full-color art.
