Scientists from the university’s Big Data Institute in Oxford It was possible to determine the place where the ancestor of all people lived. To do this, they analyzed all the biological data at their disposal, consisting of 3,609 individual genome sequences from 215 population samples.
“Essentially, we’ve built…a family tree for all of humanity…that takes into account all the genetic variants that we find in people today,” he explains. Genetics specialist Evolutionary, Dr. Yan Wong, cited in unilad.com.
The researchers used eight databases to build their original map. It shows how, step by step, some genes have been associated, over time, with other genes. The communication network dates back to prehistoric times. “The strength of our approach is that we make very few assumptions about the underlying data. The tree presents both recent and ancient samples.” Gotsays lead author of the study, Dr. Anthony Wilder and Owens.
Just as in a typical family tree, there are also distinct points here. Each of them represents a genome. On the other hand, genomes are linked to specific places on the map, as well as to the time when a particular ancestor lived in a particular area on the globe. “The genomes of the first ancestors we identified point to one geographical location… Sudan,” Dr. Wong told Reuters.
The oldest genome comes from Homo sapiens, who lived a million years ago. This contrasts with previous estimates, which had assumed Homo sapiens to be between 250,000 and 300,000 years old. A scientist from the University of Oxford explains that it was significantly different in appearance from Homo sapiens living in the 21st century.
