How exactly were 57,000 year old wolf cubs found in permafrost?

The discovery of the wolf cub was made in 2016, when a gold miner discovered an anomalous object in the process of mining, and found that it was an animal mummy, and then handed it over to the local scientific research team. After the researchers got their hands on it, they conducted an in-depth study of the environment in which the wolf cub was located and itself, and discovered a series of mysteries. <>

The reason why the wolf cub became a mummy This wolf lived 10,000 years ago, it was born in the Ice Age, only about six or seven weeks old, and the reason for its death was the collapse of the hole in the nest, after the collapse, because its body could not move, so it has always maintained that posture, plus the era and location of the Ice Age tundra, so its body has not decayed, and has not been decomposed by other organisms.

However, because it is not enclosed in the open air, the water in its body is constantly evaporating, causing its body to become a mummy. This wolf is very well preserved, the hair is still attached to the **, and the lines of the wolf's head are clearly visible. <>

The discovery of this wolf cub has made a new breakthrough in the research of the local ice age. Carnivores from 10,000 years ago were uncommon, especially with the carcasses of wolves so intact. Previously, the most primitive wolves were found in Siberia, but now there are new developments in the northern region of Canada.

This wolf is not the same species as the big bad wolf living in the local area, so researchers analyze that it may be that after the big bad wolf poured into the local area, it drove or eliminated the wolf that originally lived here, resulting in its regional extinction. <>

Scientists found that the food left in the wolf's stomach was basically mainly from the creatures in the river, including fish and shellfish. Probably because land animals were difficult to capture during the Ice Age, carnivores may or may choose river-like organisms that are easier to capture as an important source of energy**.

It was Canadian miners who accidentally discovered a frozen wolf cub while digging for gold in the Yukon, and the researchers determined through X-rays that it was a she-wolf cub who died less than two months ago. On that day, it had not yet woken up from its deep sleep, and the cave collapsed, and it had no time to hide, so it was buried in the earth, and it was buried for tens of thousands of years.

The carcass of the wolf cub was frozen forever in a layer of permafrost, which was originally discovered by a mine and immediately studied by scientists. Paleontologists estimate that the young wolf only survived for about 6 to 7 weeks.

This little wolf cub was discovered during the gold panning, and it was its appearance that provided clues for scientific and technological personnel, which is very valuable for research.

They found the wolf cub in the thawing permafrost near Dawson, Canada, and immediately protected it before they began research.

Recently, Canadian researchers found a 10,000-year-old wolf cub mummy. This suggests that mammalian populations already existed during the interglacial period tens of thousands of years ago.

Permafrost is getting more and more attention, but many people don't know what it is. Permafrost, also called tundra or tundra, means "plain without trees". In geology, it refers to various rocks and soils below 0 degrees Celsius and containing ice, while permafrost refers to the soil and rock layer that lasts for many years and freezes for two or more years.

Permafrost can be divided into short-term, seasonal, and permafrost. Permafrost, seasonal and short-term permafrost areas on Earth cover about 50 per cent of the land area, and permafrost covers 25 per cent of the land area. A typical permafrost surface has some soil or vegetation cover, called the active layer, because it can melt and freeze, changing with temperature.

Underneath the active layer is a perennial frozen rock or soil, known as permafrost, and the temperature of this layer is relatively stable, maintaining below 0 degrees Celsius. The area with permafrost accounts for about 24% of the land in the northern hemisphere, and in addition to the polar regions, it is also distributed in higher altitude regions such as the Qinghai-Tibet Plateau in China.

The thickness of the permafrost gradually decreases from high to low latitudes until it disappears completely. Permafrost has an important impact on hydrological processes and vegetation, and many areas of the circumarctic region are relatively wet, but the annual precipitation is only 150-250 mm, which is precisely because of the presence of permafrost, which prevents the circumarctic region from becoming a desert. Permafrost prevents water from infiltrating, so water is trapped on the surface to form swamps and ponds, which provide water for plant growth.

The permafrost of the Tibetan Plateau is also conducive to retaining soil moisture and thus facilitating vegetation growth.

Permafrost interacts with soil moisture and vegetation growth. Good vegetation growth will reduce soil temperature through shading effect in summer, and vegetation growth will increase soil organic matter content, reduce soil thermal conductivity, and also have a protective effect on permafrost.

The significance should be very significant, in fact, it tells us that long before human history was recorded, there were many lives.

The anti-corrosion properties of permafrost are very high.

This happened in Canada, where researchers have begun mining their country's permafrost and found specimens of wolf cubs 57,000 years ago in the permafrost. According to scientists who tested the sample for carbon-16, it is estimated that the wolf cub will live for about 6 to 7 weeks, and the specific cause of death is unknown. At present, this specimen with a little wolf cub has been preserved in the museum by Canadian researchers ** for study, this specimen of a little wolf cub can give us an understanding of the animal living environment more than 50,000 years ago, and can also determine what the biological living environment was like before 57,000 years ago through the microbial content in the specimen of the wolf cub.

It can be said that this is a taxidermy with great scientific value.

Many of you may not understand what permafrost is. Speaking of permafrost, we probably understand that 1 3 of Russia, the closest to us, has permafrost. In other words, the soil is frozen due to the very cold temperature, and the permafrost layer is the layer of soil and rock that lasts for many years.

In fact, the permafrost layer can be divided into two structures, the upper layer will melt due to the temperature in the summer every year, which is called the activity field, and the lower layer is in a permanent frozen state, that is, we call the permafrost layer, the permafrost layer will gradually disappear with the latitude, decrease, we will never find the permafrost near the equator, and the average annual temperature of the Arctic and Antarctic is only about minus 15 degrees, so the permafrost here is very thick, and the permafrost layer can not build buildings that will cause building deformation. But it's a scientist's world, because it's a place where hundreds of animal carcasses are sealed.

Although these carcasses are of great scientific value, it is actually very dangerous to mine them, because while the carcasses are frozen, some ancient bacteria and viruses are also frozen. However, due to the short survival time of our human beings, we do not have an immune system against this ancient bacteria, and mining this ancient animal carcass can easily cause the spread of the virus.

This incident has aroused heated discussions among many netizens, and has also aroused a lot of attention in the field of biological science research, because of this matter, he is of great significance to biological science research, and we can analyze it from the following three aspects.

First, it is possible to judge the differences between previous organisms and modern organisms from an evolutionary point of view.

This is the most obvious significance, because if we find the remains of a wolf cub 57,000 years ago, we can conduct a scientific analysis of its various bones and fur, and establish a three-D model, because there are still wolves in the real world today, so after more than 50,000 years, what are the specific slight changes, or whether the wolf pack has evolved, this will have an obvious answer in biological science research, which is a very obvious contrast. So the meaning is more obvious.

Second, it is possible to infer the specific surrounding environment more than 50,000 years ago.

Because we know that for the study of ancient times, we have always compared and reconstructed these hypotheses based on the analysis of fossils and soil layers, but now that we have found the remains of a wolf cub from 57,000 years ago, we can deduce some of the environmental characteristics of the time and the hunting characteristics of the time according to his physical state, hair and paw state at that time, etc. It is possible to restore the ecological environment at that time, so this is another important significance for biological science research.

Three. Able to refine the theory of evolution.

In fact, we have learned a lot about the theory of evolution in the past, and we are convinced of this view, so what factors are affected by evolution, including the speed of evolution? What are the most critical enablers? In fact, we are still relatively vague, so this little wolf cub is one for us to perfect the theory of evolution.

His actual speed of advancement and the environmental factors to which it is subjected, this study is of great significance.

The evolutionary process of the wolf species can be studied to fill in the gaps in some biological information in evolutionary research. It is possible to study other species that were symbiotic at that time by dissecting the carcass of wolves.

The discovery of this 57,000-year-old wolf cub is helpful for scientific research in human paleontology, including the physiological structure, diet and rest habits of ancient wolves, etc., for example, according to the biologists' dissection of the wolf cub's remains, it was found that the wolf cub actually fed on salmon, which was a very shocking thing for scientists.

Discover a wolf cub from 57,000 years ago. This is a good sign for biological research. It is possible to study it in contrast. Genetic changes in animals 57,000 years ago. and evolutionary history. It can also allow humans to learn more about prehistoric creatures.

YesAccording to ABC, a recently published study showsIn the thawing permafrost near Dawson City in the Yukon Territory, Canada, researchers have discovered a 10,000-year-old wolf cub mummy。This suggests that mammalian populations already existed during interglacial periods tens of thousands of years ago.

While the mummified fossil remains of large mammals have been found in Siberia, they are less common in Alaska and the Yukon. The wolves belong to a population that is related to both Alaska and Eurasian wild wolves, but not to the wolves that live in the Yukon today. According to National Geographic, the findings indicate that the first gray wolves in the Yukon went extinct and were subsequently replaced by other populations.

According to foreign media reports, Canadian researchers released a study saying that they found a 57,000-year-old wolf cub mummy, which quickly attracted widespread attention in the world. This mummy, which is so old, is very valuable for human research, and human beings can gain more relevant knowledge about ancient times and the evolution process. Of course, this may not be good news for humans, after all, a lot of viruses may be released at that time.

Discover the wolf cub mummy

In 2016, a local miner found a wolf cub mummy in the permafrost, and the wolf cub's carcass was very well preserved, even the contents of the stomach were well preserved, which is very valuable for scientists to study, and can even deduce the way the wolf cubs lived at that time, which also allows scientists to study the ice age ecosystem from another angle.

What is permafrost

Permafrost, also known as permafrost or permafrost, is a type of soil that needs to be frozen for many years over a long period of time. Generally in the two-level extreme cold area, the formation conditions need to have extremely low temperatures at the same time, and the duration is very long, even hundreds of years, thousands of years, and the two conditions are indispensable. Permafrost can release huge amounts of greenhouse gases carbon dioxide and methane, and once thawed, plants, animals, etc., that were once frozen underneath will rot, thus affecting the environment.

My opinion

The fact that well-preserved wolf mummies can be found in the permafrost is both good news and bad news for humans. Boarding mummies allows humans to study a lot of things from ancient times, but they also indicate that global warming is getting worse. Some experts have said before that if global warming, many ancient viruses may be released, and human beings do not know much about ancient times, and once these viruses are released, it will be a devastating disaster for mankind.

The discovery of the wolf cub mummy also reminds us to protect this earth and protect the place where we live.

I think that's a big discovery. This can understand some of the living habits of animals 57,000 years ago, so as to know only the climate and environment at that time, and provide evidence for prehistoric research.
