The research revealed by humanity comes from two people

The discoveries of the researchers disrupt the understanding of human evolution. According to the researchers, all modern humans only come from a pair of creatures. Like Adam and Eve?

Before reaching this conclusion, let's explore.

The study was conducted by two scientists, Mark Stoeckle of the Rockefeller University of New York and David Thaler of the University of Basel in Switzerland. The results of the research are published in the journal Human evolution.

Stoeckle and Thaler trace the human lineage and discover that it comes from two adults who lived between 100,000 and 200,000 years ago.

Not only do modern humans come from couples who "revive" humanity, but researchers have also hypothesized that extinction events are catalysts that revive the cycle of life on Earth .

Before reaching this conclusion, Stoeckle and Thaler observed and badyzed five million mitochondrial DNA data of animal origin from the 100,000 species. Mitochondrial DNA is inherited from the mother and can contain important genetic and evolutionary information.

The results show that not only humans belong to one pair of creatures, but also nine out of ten animal species.

Speaking of evolution, modern humans and many other species are about the same age. Because research shows that most of life on Earth experienced a first jump less than 250,000 years ago.

"When humans give such importance to individual and group differences, perhaps we should spend more time studying our similarity, including animals," said Stoeckle.

Given the most significant known extinction event that occurred 65 million years ago, this research has given rise to more questions than answers to history and to the cycles of life on Earth. Further research can help to explain what triggered the emergence of humans and many other species.

Thus, the research conducted by Stoeckle and Thaler does not prove the theory of Adam and Eve. In addition, a number of other evidence show that the human population in the past is still well over two.

This study deals with the coding of DNA, a technique consisting of reading a small fragment of DNA from an organism and using it to identify its species. To identify animals, geneticists generally observe the cytochrome oxidase 1 (CO1) gene.

This gene is not part of the "main" genome stored in the nucleus of animal cells, but carried in the mitochondria. Mitochondria are small sausage-shaped organs that swarm in animal cells and give them energy.

It should be noted that coding of DNA is not the ideal method for identifying species. However, the results are pretty good.

Indeed, the animals belonging to one species generally have an almost identical CO1 gene, different from that of the other species.

Because the CO1 gene is very similar in one species – regardless of the number of individuals – Stoeckle and Thaler think that something has made them so.

It could be that evolution encourages in one way or another each species to have its own version. Or almost all the genetic diversity of each species is extinct. This implies that the population has always been very weak.

It should also be noted that this problem seems to be occurring between 100,000 and 200,000 years ago. This involves a kind of global event, a non-specific disaster that reduces the population of almost all animal species.

Thaler was quoted Fox News "All animal life experiences an impulse of growth and stasis or is almost extinct at the same time scale."

According to Thaler, this can be explained by "the ice age and other manifestations of environmental changes, infection, predation, competition from other species for limited resources and interaction between these forces ".

This event, no matter what it is, also affects humans. According to research, human genetic data is consistent with the extreme extraction of two living things.

The human idea is reduced to only two people who must then replenish this planet must attract people's attention. But this idea is almost certainly wrong for several reasons.
