Exploring the Phenomenon of Neanderthal through Scientific American

By:Admin on 2023-06-20 04:08:38

In recent years, scientists have made remarkable discoveries about our ancient ancestors, the Neanderthals. These now extinct species of hominids lived in Europe and western Asia from approximately 400,000 to 40,000 years ago. While they may have been gone for over 40,000 years, their influence has left a lasting mark on modern humans.Research has shown that when modern humans migrated out of Africa around 50,000 years ago and settled in Europe and Asia, they interbred with the Neanderthals who lived there. This means that many of us today carry DNA that was inherited from our Neanderthal ancestors. In fact, it is estimated that between 1-4% of the DNA in non-African populations today comes from Neanderthals.What's fascinating is that this DNA has been found to play a significant role in our health and physical characteristics today. For example, some of the genes inherited from Neanderthals have been linked to a better ability to fight off infections, while others have been associated with an increased risk of developing autoimmune diseases.A recent study published in the journal Science has shed new light on the influence of Neanderthal DNA on our health. The study found that some of the Neanderthal DNA found in modern humans is associated with an increased risk of severe COVID-19.The researchers looked at the genomes of over 3,000 people from Europe and Asia with severe COVID-19, as well as over 9,000 people without the disease. They found that a specific segment of DNA on chromosome 3 was strongly associated with an increased risk of severe COVID-19. This segment contains a genetic variant that was inherited from Neanderthals.The study found that around 50% of people in South Asia and 16% of people in Europe carry this particular genetic variant. This suggests that the Neanderthal DNA that is present in many modern humans could be a contributing factor to the severity of COVID-19 cases in some populations.This is not the first time that Neanderthal DNA has been linked to disease susceptibility. Studies have also shown that some of the genes inherited from Neanderthals are associated with an increased risk of depression, nicotine addiction, and certain types of cancer.But it's not all bad news. Researchers have also found that Neanderthal DNA can be beneficial in some cases. One study found that Neanderthal DNA may have played a role in the development of a strong immune system in modern humans.Another study found that some of the Neanderthal genes involved in skin pigmentation may have contributed to the variation in skin color seen in modern humans today. This suggests that the interbreeding of Neanderthals with modern humans may have played a role in the evolution of human skin color.Overall, the influence of Neanderthal DNA on modern humans is a complex and fascinating topic. While some of us may have inherited genes that increase the risk of certain diseases, others may have inherited genes that have positive effects on our health and physical characteristics.As researchers continue to uncover new information about our ancient ancestors, it's clear that the legacy of the Neanderthals lives on in all of us.
