A human child “became more ape than human” with a chimpanzee before tragically killing himself later in life.
Animal psychologist Winthrop Niles Kellogg and his wife Luella conducted a bizarre experiment in the 1930s when they raised Gua and their son Donald, a chimpanzee, as “brother and sister”.
However, the couple got more than the deal when it was actually their son Donald who eventually became more ape than man.
The experiment had to be canceled because the tot reportedly started making chimpanzee-like noises and becoming more aggressive even when biting people.
He grunted and barked like his “sister” when he wanted more food and imitated his behavior.
Donald also began to move around like a chimpanzee – and the two would wrestle like two wild animals.
Seeing what was happening to his son, Kellogg’s ended the experiment—and Gua was sent away, dying of pneumonia a year later at the age of 3.
And while not much is known about Donald, he later killed himself in 1973 at just 43 years old.
On June 26, 1931, Kellogg’s welcomed his new arrival, a baby chimpanzee named Gua, whom he would raise with Donald.
There was a bid to see if the environment would affect the development of chimpanzees – and how they could humanize it.
The trial was due to last five years – but it was dropped after only nine months.
Other theories as to why the test was dropped include claims that it was canceled because Gua was growing too strong and may have harmed Donald.
Gua was seven and a half months old and Donald was 10 months old when the trial began.
And both babies were subjected to brutal trials such as being hit on the head with spoons, circling in chairs, and being teased by their parents.
Kellogg was fascinated by babies raised in the wild with little or no human assistance—and he found bringing a chimpanzee into his home was the best way to try and replicate it.
“What would be the nature of the resultant person who had matured … without clothing, without human language and without association with others of his own kind?” He asked in his 1933 book, The Ape and the Child.
He knew that releasing a human child into the wild was morally reprehensible, so he opted to introduce a baby animal into modern society.
For the next nine months, 12 hours a day, seven days a week, Kellogg and his devoted wife — both comparative psychologists — conducted test after test on Donald and Gua.
They were raised exactly the same way: they both wore baby huskies, to sit in a high chair, sleep on a bed and kiss good night, although Gua was carried around in a buggy.
Our final concern is why the project ended when it was finished.
Gua was taught the kinds of things a loving parent would do to a baby girl.
At each time, Kellogg ran a barrage of tests and measured Gua and Donald’s “blood pressure, memory, body shape, scribbling, reflexes, depth perception, vocalization, locomotion, tickle response, strength, manual dexterity, problem solving, fear of began to investigate balance, play behavior, climbing, obedience, grasping, language comprehension, attention span, and others,” notes the psychological record author.
according to a report goodIn this, Kellogg’s will tap Donald and Gua’s heads with a spoon to hear the difference in their skull sounds and make a loud noise to see who will react faster.
He even tried to persuade Gua not to eat soap bubbles and jammed the bar of the product in his mouth.
Horrible footage of the experiment shows Gua and Donald sitting on high chairs and walking around until they start crying.
They were also pushed to undergo brutal trials in which they were put through a maze and forced to pass out, while the perimeter around them changed.
For a time, Gua excelled in these exercises compared to Donald; But when they both became one, things started to change.
Donald’s ability to form words gradually eclipsed Gua’s physical benefits, and doctors soon realized that he had hit the limit of a chimpanzee’s intelligence.
The authors of The Psychological Record stated that Kellogg’s use “was ahead of its time in demonstrating the heredity of limitations placed on organisms regardless of environmental opportunities as well as the developmental benefits that could be made in an enriched environment.” better successful”.
But the experiment suddenly came to an unexplained end, with the publication stating, “Our final concern is why the project ended when it was done.
“We are only told that the study was terminated on March 28, 1932, when Gua was returned to the Orange Park primate colony through a gradual resettlement process.
“But why, Kellogg’s, who is so specific on so many other points, leaves the reader wondering.”
There were rumors that they were simply tired of nine months of non-stop parenting and scientific work.
Gua showed no signs of learning a human language, but Donald, on the other hand, had begun imitating his chimpanzee’s noises.
“In short, the language retardation in Donald may have ended the study,” The Psychological Record authors wrote.
What’s more, OZY reports, Luella Kellogg became increasingly concerned Donald was becoming more chimpanzee than human.
Gua and Donald wrestled in a way that looked more chimpanzee-like and taught his older brother how to spy on people under doors.
Donald started biting people and crawled like his sister. When he wanted to eat more he started grunting and barking like him.
Winthrop continued to work at Florida State University, where he researched bottle-nose dolphins and sonar until his retirement in 1963.
He and his wife Luella both died in the summer of 1972.
