Study reveals that Neanderthal DNA could be the reason someone likes to get up early!

There are many people who hate getting up early, while others simply love it. The second audience seems extremely strange to the first, but, according to scientiststhis behavior may have an unusual reason: genes inherited from Neanderthals.

This distinct species of hominid lived with the Homo sapiens thousands of years ago, but became extinct.

The reasons for this event are still the subject of extensive debate in the scientific community, but it is already known that there were crossings between the species.

In short, we modern humans have their genes too. This is proof that, at least at some point in history, reproduction occurred between different types of humans.

It is estimated that we may have up to 4% of DNA derived from this group, which includes structures that affect skin and hair color and immunity. Such influence could be seen more intensely among Latin Americans and Europeans.

However, scholars from the University of California, in the United States, claim that this inheritance is also capable of determining the body’s biological clock, by stimulating a predilection for waking up early.

What is the reason for these differences in the biological clock?

The theory mentioned above was defended in an article published by the magazine Genome Biology and Evolution, a respected scientific communication vehicle.

According to research, the tendency for a Neanderthal had to like getting up early is due to its different evolution compared to other hominids.

Such primitive specimens lived in Eurasia around 400 thousand years ago and more than 700 thousand years ago they separated from other humans. This large window of time caused them to adapt to completely different environmental conditions.

Thus, the region inhabited by Neanderthals it was located at higher latitudes, which meant that the number of hours of daylight was more variable than in other places. Thus, the level of luminosity and its pattern have biological and behavioral consequences in living beings.

Thanks to this, some evolutionary adaptations may arise with the capacity to modify the DNAas the study in question demonstrated.

Other humans began arriving in Eurasia when they migrated from Africa just 70,000 years ago. They then became subject to the same conditions as their ‘distant relatives’. At that time, interspecies crossing occurred, according to scholars.

Variants of this process adapted to the new environment and those that favored the morning mood were assimilated into the characteristics of modern humans.
