Shocking discovery of Adam and Eve

A new study finds that Adam and Eve - the most recent ancestors of humankind, lived in Africa at the same time, but probably never met.

"Y-chromosomal Adam" and "Mitochondrial Eve" are considered two individuals who passed on their genes to most humans, so the most recent common ancestors of men and women. However, many aspects of their existence, including the chronology, are still a mystery to the scientific world.

Previously, researchers still believed that Y-chromosomal Adam and Mitochondrial Eve lived in different periods. However, the latest study of 69 men from all over the world discovered that Y-chromosomal Adam could be present on Earth about 120,000 to 156,000 years ago, much earlier than conjectured. before.

" Y-chromosomal Adam" and "Mitochondrial Eve" are also briefly referred to as "Adam and Eve" - the most recent ancestors of men and women - in fact, those who successfully transmitted their genome through Thousands of years for most of us today.

Researchers once thought that Y-chromosomal Adam lived 50,000 - 115,000 years ago. Even so, the new discovery brought the human ancestors closer to the point of existence of Mitochondrial Eve - who is thought to appear on our planet 99,000 - 148,000 years ago. However, they are less likely to live exactly the same time, so they probably never met.

To draw this conclusion, the research team from Stanford University (USA) compared the variations of Y chromosome (including recent variants) in men from 9 different regions across the globe. , such as Namibia, CH Congo, Gabon, Algeria, Pakistan, Cambodia, Siberia and Mexico.

Even so, despite the nickname "Adam and Eve" , reminding the couple who have children residing around the world, they are not the only men and women living at that time or The only person with descendants exists to this day.

Adam and Eve are simply those who have been fortunate to successfully transmit the Y chromosome and mitochondrial genome over thousands of years to most modern humans.

Professor and genetic expert Carlos Bustamante, a research team member, said: "We can now date a number of events correctly. We found a single variation on The gene helped reveal three ancient human lines that merged about 48,000 years ago, deviating only a few hundred years. "

Another researcher added that, in the process of evolution, some human strains died out and died, while others successfully resisted and transmitted their genomes to countless generations. But it is also possible that some elements of human demographic history have made merger-like lines one at a time.
