How a baby raised as a monkey's 'brother' became 'more ape than man' in twisted experiment – and ended in tragedy – The Sun
A twisted 20th century experiment that involved raising a human baby next to a chimpanzee ended in horrifying tragedy.
The sick experiment, conducted by animal psychologists Winthrop Kellogg and his wife Luella, was abruptly halted after the scientists noticed disturbing results.

The couple left on a bizarre experiment to raise their son Donald with a female chimpanzee as “siblings”.
Gua was seven and a half months old and Donald was slightly older at ten months when the process began.
Kellogg, fascinated by children raised in the wild with little to no human help, wanted to do more research on their behavior and its effects on other people. animals.
“What would be the nature of the resulting individual who had come of age…without clothing, without human language, and without association with others of his kind?” he asked in his 1933 book The Ape and the Child.
The psychologist knew that it would be morally reprehensible to abandon a human child in the wilderness, so instead he chose to bring a young animal into modern society.
On June 26, 1931, Kellogg and his wife brought home baby chimpanzee Gua in an attempt to see if the environment would affect a chimpanzee's development – and how human they could make it.
They began raising their son Donald and Gua together as if they were both natural siblings.
For the next nine months, Kellogg and his devoted wife, both comparative psychologists, administered test after test on Donald and Gua twelve hours a day, seven days a week.
They were raised exactly the same way: they both wore baby onesies made for sitting in a highchair, slept in a bed and were kissed goodnight, although Gua was driven around in a small cart.
Gua learned what a dear parent would do with a daughter.
Meanwhile, Kellogg performed a barrage of medical tests on both babies.
Authors in The Psychological Record note that the distorted mind affects blood pressure, memory, body size, scratching, reflexes, depth perception, vocalization, locomotion, responses to tickling, strength, dexterity, problem solving, fears, balance, play behavior, climbing, obedience , grasping, language comprehension, attention span”.
Kellogg and his wife tapped Donald and Gua's heads with spoons to hear the difference in the sound of their skulls and made loud noises to see who would respond faster.
They were also forced to complete cruel trials in which they were led through a labyrinth and forced to get out as the boundaries around them changed.
They even tried to convince Gua not to eat soap bubbles by putting a piece of the product in her mouth.
Creepy footage from the experiment shows Gua and Donald being put in high chairs and spun around and around until they start crying.
Other chilling experiments
HISTORY has witnessed some of the most shocking cases of twisted minds conducting horrifying experiments on humans and animals.
Disturbing results
While Gua excelled in most of the tests Kellogg and Luella administered, things took a shocking turn when both Donald and Gua became one.
Gua's physical advantages were slowly eclipsed by Donald's ability to formulate words and the doctors soon realized that they had reached the chimpanzee's intelligence limit.
Gua and Donald wrestled in a more chimpanzee-like manner and she had taught her older brother her mannerisms.
Donald started biting people and crawling like his sister. He growled and barked just like them when he wanted more food.
He growled and barked like his “sister” when he wanted more food and mimicked her behavior.
Donald also began to move on all fours, just like the chimpanzee, and the two even wrestled like two wild animals.
When they saw what was happening to their son, the couple pulled the plug on the five-year experiment in just nine months – and Gua was sent away.
Just a year later, Gua died of pneumonia at the age of three.
And while not much else is known about Donald, he later committed suicide at the age of 43.
Kellogg continued his work on animals psychology at Florida State University, where he conducted research on bottlenose dolphins and sonar until his retirement in 1963.
He and his wife Luella both died in the summer of 1972.
