Crying boy pictured being raised with chimp in sick 'experiment' with tragic ending Chilling photos show a tiny little baby being raised alongside a chimp in a warped experiment.
However, it only lasted nine months, and the parents began to fear the worst when little Donald began biting, crawling like a chimp and grunting when he was hungry.
They already had a little boy called Donald but they wanted him to have a “sibling” – and this is where a baby chimpanzee called Gua came into the picture.
One haunting picture even showed Donald screaming out after his rotating chair was repeatedly spun in one alarming test.
Being animal psychologists, they thought it would be interesting to raise Gua alongside Donald to see how “human” they could make it.
