Paperback. Condition: New. Print on Demand. This book examines how the removal of the testicles affects sexual characteristics in birds, using cocks as case studies. The author, a distinguished scientist, provides an in-depth analysis of the role of the testes in the development of secondary sexual characteristics, such as the comb, wattles, and spurs, in addition to behaviors like aggression and courtship rituals. Through meticulously designed experiments, the author demonstrates that the removal of the testes early in development leads to the suppression or alteration of these characteristics, challenging the long-held belief that they are solely determined by genetics. This groundbreaking work not only furthers our understanding of the relationship between hormones and sexual development but also has implications for comprehending the evolution of sexual characteristics and behaviors across species.
