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.
