(#10) Scientists Tried To Create A "Humanzee"
Russian biologist Ilia Ivanovich Ivanov, using a grant from the Soviet Government, sought to create a hybrid of a human and a chimpanzee – colloquially known as the "humanzee" – in an African lab in 1926. First, he tried to impregnate chimps with human fluids. When this failed, he planned to inseminate human women with chimp fluids.
Ivanov did manage to find a few women willing to carry a chimp baby, but all of his chimps passed in transit, and he passed in 1932 as a result of a purge of scientists.

(#11) A Turkey Head Mounted On A Stick Tested Turkey Mating Rituals
Martin Schein and Edgar Hale of the Pennsylvania State wanted to study what attracts one turkey to another. They started in the early 1960s with a female turkey model, removing parts one by one to see when the male would lose interest.
Left with a fake head on a stick, they took the next step and replaced the model with an actual female turkey’s severed head to test the results. The male turkeys attempted to mate with head regardless of its stick body.

(#9) Two Dogs Were Brought Back To Life
University of California researcher Robert Cornish believed he could revive non-living organisms as long as their organs were intact. As part of his 1934 "Lazarus Project," he terminated five fox terriers and placed them in a homemade machine that circulated their blood – while simultaneously circulating a cocktail of adrenaline and anticoagulants. Cornish actually revived the last two dogs, which, though they suffered from severe brain damage, lived on for several months.
Cornish’s research passed with the dogs, however; he was disgraced for his research and dismissed from his university position. For a time, he did intend to repeat the experiment with a human volunteer .

(#15) The Brains Of Kittens Were Replaced With Zinc And Silver
In the early 19th century, German researcher Carl August Weinhold sought to prove that the brain and nervous system were attached to one another by wires. To test his hypothesis, he removed the brains and spinal cords of several decapitated kittens and filled the cavities with zinc and silver pile batteries.
The resulting electrical charge caused the kittens' bodies to leap around for several moments before passing.

(#5) Cartilage Cells Grew A Human Ear On A Mouse's Back
Nicknamed the “Vacanti mouse” for the project's lead scientist, this mouse was seeded with cow cartilage cells that had been molded into an ear shape. The result of this 1997 experiment was a disproportionate, human-ear-shaped growth on the mouse's back.
The growth was eventually removed, and the mouse went on to live a "happy, normal life." The purpose of the study, though sensationalistic at first glance, was to improve reconstructive plastic surgery techniques.

(#3) Cancer Researchers Made Frogs' Skin Transparent
To help further their insight into organ growth and tumor development, in 2007, Japanese cancer researchers at Hiroshima University actually bred transparent frogs. These frogs boasted internal organs that were completely visible through their skin.
Apparently, this innovation allows researchers to reduce the number of dissections they have to perform, since the frog's internal organs and blood vessels are all visible through their skin.

About This Tool
Animal experiments have been controversial for hundreds of years, but they have widely influenced the scientific exploration of physiology, genetics, and diseases in modern medicine. Although animal experiments have helped countless scientists achieve brilliant scientific achievements, they have also inspired many people to criticize unethical experiments, even the most conservative experimental estimates.
Although scientists have developed alternative animal experiments in recent history, there are still researchers who have conducted a large number of crazy experiments on unsuspecting animals, monkeys, dogs, rats, etc., are common subjects. The random tool introduced 17 crazy animal experimentations throughout history that most people don't know.
