From Library Journal
Since the time of Darwin, altruism and other forms of cooperation have puzzled evolutionary biologists. Several theories have been proposed to explain these behaviors, but each has weaknesses in the framework of traditional natural selection. The Zahavis, working with babblers (group-living birds), developed the handicap principle and signal selection to explain these apparent paradoxes. (Their theory proposes that when an animal behaves altruistically, it does so to increase its status within its group as a partner or rival.) This book presents their evidence, elaborated in many technical papers since the 1970s, to explain such behaviors in babblers and such diverse organisms as slime molds, social insects, peafowl, and human children playing tag. The handicap principle is an important new theory that explains many seemingly diverse problems in evolutionary biology. This book is highly readable yet rigorous enough for specialists. Essential for any academic collection and worthwhile for general collections.?Bruce D. Neville, Univ. of New Mexico Lib., Albuquerque

Review
The Handicap Principle analyzes signaling between organisms and its evolutionary role....[It] fills a rare niche in scientific books-namely a book in which the scientific ideas are presented honestly and accurately, in a clear and interesting way, without talking down to non-specialists....I applaud the Zahavis for a job very well done. -- Walter J. Bock, BioScience

5.0 out of 5 stars Best book on evolution in many years, May 19, 2000

By	Dennis Littrell (SoCal) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)    (COMMUNITY FORUM 04)

Why does the peacock grow that tail? Why does the springbok leap straight up into the air when it sees a predator? Why do people behave heroically? The handicap principle answers these questions, eloquently, simply and with an overwhelming sense of conviction. The peacock is advertising his fitness. He is saying to the female in essence, I am so fit I can carry around this cumbersome adornment and still scratch out a very fine living. The springbok is saying to the predator: don't even think about going after me. I am in such good shape I can waste energy jumping up and down and still have plenty of reserves to outrun you. Save us both the bother and go after someone weaker. (By the way, the springbok jumps straight up instead of sideways because by jumping straight up its performance can be effectively judged by a predator from any direction.) And the man who dives into the swiftly flowing river to save a drowning child is actually advertising his fitness and improving his station in society. He is so fit he can take chances that others dare not. He's the man the women want to mate with.

The Handicap Principle thus is about signals, signals between prey and predator, between one sex and the other, and between the individual and the group. The purpose of these signals is to display in an unequivocal way the fitness of the signaler. Note that such signals have to be "fake proof." They have to be what the authors call "reliable." An animal that can't run fast and has limited resources of energy can't waste them jumping in the air. It needs to get going immediately or to stay hidden if it is to have any chance of survival. A man leads with his chin. That's a signal that he's confident. When men had beards it was a little dangerous to stick your chin out since the other guy might grab your beard and you could be in trouble. People demonstrate wealth by wasting money. This is a "reliable" (if ugly) signal because without an ample supply of money, you can't afford to waste it.

Part of the beauty of this book comes from the personality of the authors, who spent a large part of their lives studying little babbler birds in Israel. I feel I know these little social birds just from the loving descriptions in the text. One can see that even though the Zahavis made their discovery of the handicap principle in 1975 and waited almost two decades before it was generally accepted in the scientific community, they harbor no bitterness, nor is their tone at all gloating. They come across as hard-working field scientists who love their work and nature.

Besides being full of exciting and original ideas, The Handicap Principle is also extremely well written. Each sentence is clear and to the point without the burden of unnecessary jargon or the wordy clumsiness sometimes found in such books. Amotz and Avishag Zahavi took great pride in effectively communicating their ideas to a wide audience. Additionally there are scores of exquisite, loving little black and white drawings by illustrator Amir Balaban of animals, birds, insects and people, etc., illuminating the text.

If you're interested in evolutionary theory, this is a book not to be missed. As Jared Diamond says on the cover, "Read this fine book, and discover what the excitement is all about."

5.0 out of 5 stars I loved it, insightful, entertaining, astounding., May 5, 1998

By	[e-mail] (Albuquerque, NM USA) - See all my reviews

This very readable book covers a wide range of biological behavior, and really demonstrates the reality of the Handicap Principle. Not only am I convinced of its truth, but now understand much more about human behavior than before.

4.0 out of 5 stars Think natural selection is cool? This will expand your mind., February 25, 1998

By A Customer

A compelling addition to the literature on natural selection and evolution. The Handicap Principle illustrates with compelling examples the reasons for the evolution of much animal behavior, coloring, and communication. A bit heavy on zoology for non-natural scientists, it however is a must read if you fancy yourself a student of evolution.
