“There was no Adam and Eve”… The monogenetic theory of human origin that loses its power
“There was no Adam and Eve.”
The conventional wisdom that modern humans originated somewhere in Africa is breaking. Searching vast amounts of genetic data with computer models reveals that humans did not originate in one place, but have been mixed through various exchanges while moving for millions of years.

An international joint research team, including the University of Wisconsin-Madison, USA , published the results of this research in the international journal Nature on the 17th (local time). The findings suggest that modern humans arose from diverse ancestral populations around the continent of Africa. In addition, these ancestral populations, which are estimated to have lived 1 million years ago, were all the same hominin race , but it is estimated that there were some genetic differences. The research team developed new computer software and analyzed
gene sequencing data of modern humans, Africans and Europeans, and Neanderthal DNA , an ancient human, to confirm this fact. Archaeological geneticists have been trying to prove the “single origin” theory for decades. By giving nicknames such as ‘Adam’ and ‘Eve’ to ancient human fossils found in Africa, claims have been made that they have found the origin of mankind. However, this single-origin theory has exposed problems that do not match the results of genetic analysis or archaeological excavation. If mankind started from one area, the closer it is to that place, the older genetic data and relics will be collected, and the farther away it will be, the opposite. In reality, however, the physical characteristics and tools of Homo sapiens appeared simultaneously throughout the African continent at about the same time.
The research team analyzed vast amounts of genetic information using software with high-capacity computing power developed by Professor Simon Gravel’s research team at McGill University in Canada. In previous studies, genetic information itself was also lacking and mainly focused on data from West Africa, failing to reflect the vast genetic diversity of the African continent. However, the research team integrated and analyzed a wide range of gene sequencing results from East and West Africa as well as the Nama people living in South Africa토스카지노. It was a way to track and understand how genes moved historically through generations. They also used variables such as migration and population merging to predict gene flow over thousands of years. In particular, this result was compared with the genetic variation seen in modern humans today, and the most consistent model was identified.
With this, the research team overturned the previous explanation that the genetic diversity of modern humans was formed by isolation after interbreeding with other ancient species from which Homo sapiens diverged. Instead, ancient hominin tribes, or human ancestors, had genetic differences, but formed localized populations by interbreeding in a given area for thousands of years. And over time, they migrated all over Africa. The research team named this research result a ‘weakly structured stem model ‘ and explained that it could more clearly explain the genetic diversity of modern humans.
