The handicap principle

Book • 1997
The Handicap Principle, proposed by Amotz Zahavi, suggests that secondary sexual characteristics and other signals are costly and thus reliable indicators of an individual's quality.

This theory provides insights into animal communication and mate choice, offering a unique perspective on evolutionary biology.

The book explores various examples, including bird songs and peacock tails, to illustrate how these costly signals function as honest indicators of fitness.
