This question refers to the early theories of the Positivist School of Criminology.
Cesare Lombroso, an Italian criminologist often called the "father of modern criminology," is famous for this theory.

Lombroso believed that these "atavistic" criminals could be identified by certain physical stigmata or traits, such as a sloping forehead, large jaws, or long arms, which he thought were indicators of a primitive nature.
