The article raises the question of the need to expand interdisciplinary links of legal science and its output beyond the socio-cultural context, in which the state-legal phenomena are most often studied. On the example of the data of evolutionary biology, cognitive and evolutionary psychology, as well as a number of other directions of modern scientific knowledge, the issues that can and should become a subject of reflection for legal scientists are outlined. At the same time, attention is drawn to the relevance of the principle of transdisciplinarity in the knowledge of the world around, including the study of law and state.

Some perspective directions of interdisciplinary research of human legal behavior and state-legal regulation are defined. In particular, the influence of the system of intuitive inferences is developed in the course of biological evolution and is not controlled by consciousness on the process of selection and perception of meaningful information (including predisposition to learning morality), on the ability of a person to form various associations and innate mechanisms of recognizing social alliances (coalitions) and control over loyalty to them, on the built-in in the mind patterns of exchange and sense of justice are outlined.
