Lombroso popularized the notion of the born criminal through
biological determinism, claiming that criminals have particular
physiognomic attributes or deformities. Physiognomy attempts to
estimate character and personality traits from physical features of
the face or the body. Whereas most individuals evolve, the violent
criminal had devolved, and therefore criminals were societal, or
evolutionary regressions. If criminality was inherited, then the
born criminal could be distinguished by physical atavistic
stigmata, such as:
large jaws, forward projection of jaw, low sloping foreheads
high cheekbones, flattened or upturned nose
handle-shaped ears
large chins, very prominent in appearance
hawk-like noses or fleshy lips
hard shifty eyes, scanty beard or baldness
insensitivity to pain, long arms [5].[6]
