[In this instance a type of brain surgery, was practiced on a cow, which was practiced quite a lot on humans. The Ancient Greeks did it, the Romans did it as did other non-whites. Scientists don’t know how much of this was based on medicine or ritual. It seems to be mostly medical related. But in Russia they found people who did it as a ritual.
Scientists could see that many people survived this process because the bone began to heal around the hole. It is incredible to think whites were trying this type of brain surgery thousands of years ago. They actually could drill through the skull of a living person. Some died during the process, but there are many who lived, and when scientists first discovered this over a century ago, they were utterly astounded by it!]
Humans Probably Practiced Brain Surgery on This Cow 5,000 Years Ago

About 5,000 years ago, humans used crude stone tools to puncture a hole in a cow’s head, making it the earliest known instance of skull surgery in an animal.
It’s unclear whether the cow (Bos taurus) was alive or dead when the operation took place, but if it was alive, the animal didn’t survive for long, given that its skull shows no signs of healing, researchers said in a new study.
However, the intent of the surgery remains a mystery. If the operation — known as trepanation, a primitive type of brain surgery — was meant to save the cow, it would be the oldest known evidence of veterinary surgery on an animal, said the study’s lead researcher, Fernando Ramirez Rozzi, director of research specializing in human evolution at France’s National Center for Scientific Research in Toulouse.

Researchers unearthed the ancient cow skull during an excavation lasting from 1975 to 1985 at the Neolithic site of Champ-Durand in Vende?e, a region on the Atlantic coast of western France. An analysis showed that the cow skull dated to sometime between 3400 B.C. and 3000 B.C., and that the animal was clearly an adult, the researchers found.
When past archaeologists first looked at the nearly complete cow cranium, they thought another cow must have caused the gouge. But the hole — which is 2.5 by 1.8 inches (6.4 by 4.6 centimeters) — was so peculiar that one of the original researchers asked Ramirez Rozzi and Froment to take a second look at it in 2012.
“At that time, we looked, and very quickly, we saw that it was trepanation in the cow skull; it was not a goring at all,” Ramirez Rozzi told Live Science.
If another animal had gored the cow, the violent blow would have caused fractures or splintering around the wound, the researchers said. And “no evidence of such a fracture, either internally or externally, can be seen,” the researchers wrote in the study. Nor does the hole look like it was caused by an infectious disease, such as syphilis or tuberculosis, Ramirez Rozzi and Froment noted.
While using a scanning electron microscope, the researchers saw cut marks around the hole in the cow’s head that looked eerily similar to scrape marks seen on the skulls of human trepanation patients, Ramirez Rozzi said.

The earliest evidence of trepanation in a human skull dates to the Mesolithic period, which lasted from about 8000 B.C. to 2700 B.C., the researchers said. Archaeologists have several ideas about why ancient people would scrape or drill a hole into a skull. Perhaps the technique was meant to solve a medical condition, such as epilepsy, or maybe it was part of a ritual, the researchers said.
In the cow’s case, it’s not clear why Neolithic people would have gone the extra mile to save a cow with some kind of medical disorder, Ramirez Rozzi said. It’s more likely that these ancient people were using the cow’s skull for trepanation practice, he said.
The study was published online today (April 19) in the journal Scientific Reports.
