strange but true

According to research This means that many humans have Neanderthal DNA. 1% to 2% are from European or Asian backgrounds, and as many as 4% are from East Asia. This is thanks to the interbreeding of humans and Neanderthals.
Neanderthals likely evolved outside of Africa, so some African populations have very little Neanderthal DNA.
Now, 40,000 years after Neanderthals went extinct, a genetic engineer has shared six physical traits and behaviors associated with Neanderthal DNA.
“Neanderthal DNA makes up only a small part of the genome of modern humans, and these influences are just one piece of the genetic puzzle that makes each person unique,” said Sebnem Anne-Lewis of the London Regeneration Institute. Mr. Rah says. told the Daily Mail this week.
Let’s take a look at their characteristics, from smoking to having straight and thick hair to being a morning person to being more likely to get infected with the coronavirus.
smoking
2016 study by Vanderbilt University researchers This is surprising because one of the lengths of Neanderthal DNA has been linked to a higher risk of nicotine addiction, and cigarettes did not become popular in Europe until the mid-to-late 16th century. .
“The brain is incredibly complex, so it’s reasonable to expect that the introduction of changes from different evolutionary pathways could have negative effects,” said Dr. Corinne Simonti, lead author of the study, said: said at the time.
having straight and thick hair
“Neanderthal DNA is linked to hair mutations Features. “Some people with Neanderthal ancestry may have slightly thicker or straighter hair,” Ann Ruisler told the Daily Mail. “Studies also show that genetic variants associated with red hair are present at higher frequencies in Neanderthals.”
getting up early
A study published last month found that Eurasian Neanderthals experienced more seasonal fluctuations than their African relatives, which affected their body clocks and made them more likely to wake up early in the morning.
“At high latitudes, it would be beneficial to have an internal clock that can better predict and adjust to changes in seasonal light levels,” said study co-author Professor of Epidemiology and Biology at the University of California, San Francisco. said Associate Professor of Statistics Tony Capra. , told CNN During December.
“Having a ‘faster’ running ability facilitates this ability, making you more likely to wake up early,” he added.
having a high nose
University College London 2023 Study Researchers have discovered that a gene inherited from Neanderthals causes the nose to grow taller from top to bottom.
“It has long been assumed that the shape of our noses is determined by natural selection. Our noses help regulate the temperature and humidity of the air we breathe, so different shaped noses may be better suited to the different climates that our ancestors lived in,” said the study’s lead author, Dr. Chin Li from Fudan University. time.
“The genes we identified may have been inherited from Neanderthals as our ancestors migrated out of Africa to help humans adapt to colder climates,” Lee continued.
Onset of severe cases of novel coronavirus infection (COVID-19)
Researchers have discovered that the mutation can occur in a segment on chromosome 3, the third largest of the 23 pairs of human chromosomes. People are more likely to develop more severe cases of coronavirus infection.
The genome segment was inherited from Neanderthals.
have a hard time tanning
In 2017, scientists at the Max Planck Institute for Evolutionary Anthropology in Germany Neanderthal allele identified — Gene variants — contribute to hair and skin tone.
“Individuals with Neanderthal ancestry may be more likely to have light or dark skin, and some people may carry alleles associated with light skin color, which may occur in areas with lower sunlight intensity. They may have increased resistance to ultraviolet light,” Ann Ruisler explained to the Daily Mail.
