Have you ever wondered why some people are able to go to bed early and wake up with the sun, while others have to sleep until late in the day? Researchers believe this may be due to an ancient Neanderthal gene.
according to Sky News Researchers at the University of California compared ancient DNA with the genetics of a man-killer and discovered what they referred to as a “striking similarity.”
The study was published in the peer-reviewed scientific journal Genome biology and evolution.
Hunting in broad daylight
Lead author and epidemiologist John Capa explains that they found the Neanderthal gene in people who are morning birds.

Neanderthals are an extinct species in the human family. The species was named after Neanderthals in Germany where fossils were first discovered in 1856, he writes. The Great Norwegian Encyclopedia (SNL).
Recent investigations of DNA from Neanderthal and modern human bones have shown that many modern humans have a small percentage of Neanderthal DNA, he said.
According to the study report’s author, people who carry the Neanderthal gene wake up early in order to “hunt as much as possible in daylight.”
Kaba believes that a gene that makes people wake up early may facilitate changing the circadian rhythm according to the seasons.

In the study, the researchers analyzed the genes of hundreds of thousands of people from the UK Biobank, which contains genetic, health and lifestyle information for half a million people, the British wrote. Watchman.
Neanderthals were hunter-gatherers, and had permanent dwellings over time. According to SNL, genetic studies show they may have lived in relatively small family groups, with women marrying into other groups. The men stayed where they grew up.
Paired
They had a body better adapted to the cold than modern humans. Neanderthals were also more powerful. This species is known in Europe and the Middle East – and as far east as southern Siberia.
Why Neanderthals disappeared is one of the most controversial questions in anthropology, the study of humans. One theory is that they fell victim to climate change, and another says that they were exterminated by their descendants – the human species Homo sapiens.
Researchers suspect that morning birds inherited the Neanderthal “internal clock gene” after modern human ancestors interbred with Neanderthals. The researchers believe the study’s results are consistent with what has been found in animals that had to adapt to live at high latitudes, as Neanderthals did.

according to SNL Neanderthals may have descended from Homo heidelbergensis, also called Heidelbergensis man.
This species got its name from the German city of Heidelberg, when in 1907 a well-preserved lower jaw of a prehistoric man was found. The Heidelbergian people lived in Africa, Europe, and the Middle East about 600,000 to 200,000 years ago.
