Neanderthal's persistent revenge

Pushed into the path of extinction tens of thousands of years ago, the Neanderthals still have the opportunity to avenge by inheriting a dangerous disease for modern people.

The Neanderthals have disappeared from the Earth's surface at least 30,000 years ago, and the genocide culprit is most likely the ancestor of modern humans, according to a long-held hypothesis. However, the new report shows that Neanderthal revenge continues to this day, by making people more susceptible to deadly diseases such as cancer and diabetes.

According to research results, Neanderthals with modern people who lived in the same era, and for thousands of years the two had the opportunity to mate with each other, resulting in Europeans today containing 2% of their DNA. Neanderthals. These genes are found to increase the risk of cancer and diabetes.

Last year, experts from Oxford University and Plymouth (UK) published the genes identified to increase the risk of cancer in the Neanderthal gene sequence, and in January of this year, Nature published its publication. Harvard University's research (USA) reveals a gene that is inherited from Neanderthals, which can cause diabetes in Latin Americans.

By examining the gene obtained from a Neanderthal toe toe bone, scientists can build a more complete version of the early human history, and explore development and evolution. of modern people.

Based on the results of DNA analysis, inbreeding has taken place very seriously in Neanderthal communities, and they also have the habit of "sleeping" with other ancient families like Denisovan.

However, in parallel with the negative effects, the blood exchange process has also enhanced the immune system of modern ancestors, helping them to cope with common diseases in the early days of human civilization. .

According to Phys.org, the head of the human-origin research project, Professor Chris Stringer of the British Museum of Natural History, said the Neanderthals have grown and grown outside of Africa in thousands. year. Therefore, their bodies must cope with the attack of many diseases that modern humans never faced.'Studies show that the modern human immune system has quickly been upgraded through the process of combining with Neanderthals, thus helping us to survive' , according to Professor Stringer. Thanks to foreign genes , modern ancestors' leukocyte antigen system supports white blood cells to identify and destroy foreign bodies.

Besides, reports show that Neanderthals fall into extinction not only because of being chased and killed by modern humans, but also because they mate and contribute their DNA to a large population. than. The trend of expanding the genetic store in modern people does not stop at Neanderthal. Some studies show that about 100,000 to 500,000 years ago, there were seven different people sharing the earth. Accordingly, people in sub-Saharan Africa own DNA from Homo heidelbergensis (aka Heildelberg), while some Asian groups receive genetic genes from Denisovans.
