Extraordinary video footage shows how two scientist parents attempted to raise their infant son alongside a chimpanzee as part of a bizarre nature versus nurture experiment in 1931.
Psychologists Winthrop and Luella Kellogg conducted the study on their ten-month-old son Donald and a seven-month-old chimp called Gua at their Florida home.
The couple were attempting to establish if it was possible to educate an ape and teach them to communicate as a human.
But the experiment, which they intended to run for five years, was abandoned after just nine months when the pair noticed chilling changes in the behavior of their son.
