The book "Adam's Language" is an interdisciplinary study of the prerequisites for the emergence of language. She poses this question within the framework of a new evolutionary theory - the theory of "the emergence of niches," which assumes the activity of animals in building niches: animals form them and form themselves, adapting to them. On this basis, hypotheses are built on why and how the need for language could arise, what was the first step from animal communication systems to the "language of Adam."
