Actually, Our Noses Come From Neanderthals, Researchers Claim

The culprit is now clear to you.

According to a notion put up by a team of University College London academics, it may have once been advantageous to be likened to a Neanderthal.

According to a recent study published in Communications Biology, the nose on a human face is descended from Neanderthal DNA. They assert that human and Neanderthal interbreeding is how that DNA got to be a part of the human genetic composition.

According to a news release from Kaustubh Adhikari, a researcher at UCL and co-author of the study, "in the last 15 years, since the Neanderthal genome has been sequenced, we have been able to learn that our own ancestors apparently interbred with Neanderthals, leaving us with little bits of their DNA." We discover that some Neanderthal DNA altered the structure of our features. Given that information has been handed down for many years, this could have been useful to our ancestors.

This same researchers discovered in 2021 that humans received a gene that affected lip shape from the prehistoric Denisovans.

The new research identified a gene that may have been passed down through generations as a result of natural selection as humans acclimated to colder regions and contributes to a higher nose from top to bottom.

Researchers discovered 33 novel genomic regions linked to face form by analyzing 6,000 volunteer volunteers' faces from various ancestries. The ATF3 genome, which is widespread throughout ancestry cohorts and is particularly prevalent in people of Native American and Asian descent, originated in Neanderthals and made a person's nose taller.

Co-author Andres Ruiz-Linares of Fudan University and UCL claims they were able to extend the scope of genetic research to discover the Neanderthal connection by looking beyond the genomes of Europeans.

Natural selection has long been thought to have a role in shaping our noses, according to research author Qing Li of Fudan University in a news release. Different nose shapes may be more adapted to the various climates that our ancestors lived in because they can assist us manage the temperature and humidity of the air we breathe in.
