This document discusses early biological theories of crime and deviance proposed by several theorists. It describes Franz Gall and Johann Spurzheim's phrenology theory that skull shape could predict criminality. It also outlines Cesare Lombroso's theories of atavism, that some are born criminals due to genetic predisposition, while others become criminaloids due to environment. Lombroso also proposed a masculinity hypothesis that over time male and female crimes would become similar. The document concludes by mentioning Charles Goring's study that disputed Lombroso's claims.
