Hereditary variation in rates of ontogenetic formation of exploratory behavior, glucocorticoid functions, and neurotransmitter systems in wild Norway rats during selection for absence of defensive response towards humans (domestication) is demonstrated. Interrelated shifts in the development of behavior and neurohormonal systems are shown. A comparison of the data obtained with the results of domestication of another speciessilver fox-suggests that equally vectorized selection of animals belonging to different taxa produces equally directed changes of their regulatory systems.
