Man belongs to a biological species, therefore he is subject to the same laws as other representatives of the animal kingdom. This is true not only of the processes occurring in our cells, tissues and organs, but also of our behavior - both individual and social. It is studied not only by biologists and doctors, but also by sociologists, psychologists, and representatives of other humanities disciplines. Using extensive material, supporting it with examples from medicine, history, literature and painting, the author analyzes issues at the intersection of biology, endocrinology and psychology, and shows that human behavior is based on biological mechanisms, including hormonal ones. The book examines topics such as stress, depression, rhythms of life, psychological types and sex differences, hormones and the sense of smell in social behavior, nutrition and the psyche, homosexuality, types of parental behavior, etc. Thanks to the rich illustrative material, the author’s ability to speak simply about complex things and his humor, the book is read with unflagging interest. The book “Stop, who is leading? Biology of Human Behavior and Other Animals" was awarded the "Enlightener" prize in the "Natural and Exact Sciences" nomination.
