Scientists in a laboratory in the Far East of Russia cut incisions and carefully collected samples, looking like pathologists after lesions.

But the body they analyzed was a baby mammoth who died about 130,000 years ago.

The Calf Discovered Last year – The river found nicknamed Yana, was found in the river she was found with extraordinary preservation. It gives scientists a glimpse of the past and possibly the future of the permafrost she was discovered as climate change melts.

Yana’s skin retains the taupe color and red hair. Her wrinkled torso bent and pointed at her mouth. The tracks of her eyes are completely recognizable, and her strong legs resemble modern elephants.

This autopsy – an autopsy of animals – is an opportunity to study our planet’s past,” said Artemy Goncharov, head of the Laboratory of Functional Genomics and Proteomics at the St. Petersburg Institute of Laboratory of Experimental Medicine.

Scientists hope to find unique ancient bacteria and perform genetic analysis of plants and spores to learn more about where and when she lives.

The calf largely avoided the destruction of time as she lay in the permafrost of the Siberian Saka region for thousands of years.

Russian scientists say that the shoulders are 1.2 meters (nearly four feet), 2 meters long and weigh 180 kilograms (nearly 400 pounds), Yana is probably the best preserved mammoth specimen ever, retaining internal organs and soft tissue.

Stomach, intestine

Dissecting her body is a treasure trove of sixty scientists who performed an autopsy at the Mammoth Museum in the Northeast Federal University, the capital of the Yakutsk region in late March.

Zoologists and biologists wore white sterile bodysuits, goggles and face masks and worked for several hours in the previous quarter of the mammoth, a species that disappeared nearly 4,000 years ago.

“We can see a lot of organs and tissues that are well preserved,” Goncharov said.

“The digestive tract is partially preserved; the stomach is preserved. The intestine remains fragmented, especially the colon,” he said, allowing scientists to collect samples.

He said they were “looking for ancient microorganisms” to preserve in mammoths, so they could study their own “evolutionary relationships with modern microorganisms.”

One scientist used scissors to cut Yana’s skin, while another scientist used a scalpel to cut an incision into the inner wall. They then placed the tissue samples in test tubes and bags for analysis.

Another table holds the mammoth’s hind limbs, which is still embedded in the cliff when it is below the current quarter.

The mammoth smell reminds the mixture of fermented sites and soaks the meat in the underground soil of Siberia.

“We are trying to reach the genitals,” said Artyom Nedoluzhko, director of the Paleontology Laboratory at European University in St. Petersburg.

Their goal, he said, is to “collect materials to understand that the microbiota lives on her while she is still alive.”

“Milk Ivory”

Yana was first estimated to die 50,000 years ago, but now has more than 130,000 years of history after analyzing the permafrost she lays down.

As for her age of death, “It’s obvious that she’s been over a year because her milk ivory has appeared.”

Both elephants and mammoths had early milk tusks, which later fell off.

Scientists have not yet determined why Yana died at such a young age.

Cheprasov said that while the herbivorous mammal was chewing the meadow, “there are no humans on the territory of Yakutia” because they appeared between 28,000 and 32,000 years ago in modern Siberia.

The secret to Yana’s special preservation is the permafrost: the soil in this area of ​​Siberia is frozen year-round, like a huge freezer, retaining the bodies of prehistoric animals.

Yana’s exposed body’s discovery was caused by melting permafrost, which scientists believe is due to global warming.

Goncharov said the microbiology of this ancient remains also explored the “biological risks” of global warming.

He explained that some scientists are studying whether the melting of permafrost can release potentially harmful pathogens.

“There are some assumptions or speculations that pathogenic microorganisms that may be retained in permafrost, which can enter water, animals and plants and humans when it thaws, as well as humans,” he said.
