In the animal kingdom, survival is the name of the game—and not everything is as it seems. A number of animals rely on particularly clever tricks to fool predators or prey. A baby bird mimics a poisonous caterpillar. A moth escapes bats by making sounds that interfere with the bats' echolocation. A tiny rain forest spider builds a big spider "puppet" out of bits of dead leaves, insect parts, and other items. Find out more about some of nature's most bizarre and bloodthirsty con artists and meet the scientists who are working to figure out just how they pull off their amazing tricks.

The psychology classic—a detailed study of scientific theories of human nature and the possible ways in which human behavior can be predicted and controlled—from one of the most influential behaviorists of the twentieth century and the author of Walden Two. “This is an important book, exceptionally well written, and logically consistent with the basic premise of the unitary nature of science. Many students of society and culture would take violent issue with most of the things that Skinner has to say, but even those who disagree most will find this a stimulating book.” —Samuel M. Strong, The American Journal of Sociology “This is a remarkable book—remarkable in that it presents a strong, consistent, and all but exhaustive case for a natural science of human behavior…It ought to be…valuable for those whose preferences lie with, as well as those whose preferences stand against, a behavioristic approach to human activity.” —Harry Prosch, Ethics
