New study reveals groundbreaking details human evolution By studying 45,000-year-old human DNA.The human genome has undergone a previously unknown and dramatic change genetic change In response to environmental pressures, it has found.

This study was published in a peer-reviewed journal on October 31. Natural ecology and evolutionmay lead researchers to discover that previously understood modes of selection in natural populations may be inaccurate, helping to better understand human evolution and genetics over time. brings

An international team of scientists led by the University of Adelaide Australiaexamined the DNA of more than 1,000 ancient genomes, the oldest of which is about 45,000 years old, and found that certain types of genetic adaptations were more common in human history than studies of modern genomes suggested. I checked to see if it was there.

“As a result, this discovery challenges the prevailing view of human adaptation and provides new and exciting insights into how humans have adapted to new environmental pressures encountered as they spread across the planet. increase.”

Dr. Yassine Souilmi, who co-led the study, explains: tool. ”

Challenging popular beliefs about human adaptation

“However, by comparing modern genomes to ancient DNA, we have found more than 50 cases of initially rare and beneficial gene variants prevalent in all members of ancient human groups. continued Souilmi.

“In contrast to many other species, the evidence for adaptive genetic change in this species is inconsistent in humans. As a result, this finding challenges the prevailing view of human adaptation.” provides new and exciting insights into how humans have adapted to the new environmental pressures they have encountered as they spread across the planet.”
