Between 2003 and 2011, after studying a DNA database of more than 6000 individuals around the world, geneticists Wells and then Cruciani concluded that humans living on Earth today all descended from same ancestor : a homo sapiens living on the African continent 60 to 000 years ago. He is nicknamed "the Y-chromosomal Adam", (for the one who gave his Y chromosome to all modern humans) or more simply "the genetic Adam".
Lhe same observation could be made for women from the mitochondria of cells, thus, the first woman known to date (ie their oldest common ancestor) is called "the mitochondrial Eve". Scientists agree that humans first appeared on Earth around 200 years ago.
However, in 2013. , the study of the DNA of Albert Perry, a man of African American origin who lived in South Carolina, came to upset this quasi-certainty of the scientific world. Indeed, the analysis of his DNA first reveals that his Y chromosome is not linked to the genetic Adam, but is part of another older line. This lineage dates back to 340 years, well before the supposed appearance of man on Earth!
Michael Hummer, geneticist, has an explanation to this extraordinary discovery: an "archaic" line would have survived for many years instead of dying out as is usually the case admitted, until coexisting alongside homo sapiens. Crossbreeding of these two lines would have allowed the transmission of Albert Perry's Y chromosome.
A thesis supported by the recent discovery, in 2011, of a primitive skull in Iwo Eleru in Niger. Although it was dated to about 13 years ago, the bones of the skull exhibited much more primitive features; which suggests once again that the primitive African descendants did not become extinct to give birth to modern man, but that the two species would have cohabited and reproduced.
These discoveries are not the first to question Darwin's theory of evolution, which advocates linear evolution made up of hazardous mutations and natural selections. According to M.-P. Schutzenberger, a famous mathematician keen on science, evolution as presented by Darwinism has many flaws, because the mere existence of DNA is not enough to explain the evolution of man from the primate:
“[Darwinism is] entirely incapable of giving a convincing explanation for the near simultaneous emergence of the many biological systems that distinguish man from higher apes: bipedalism […], a much more skilled hand, with fingerprints which give it a much finer touch; modifications of the pharynx allowing phonation […]. It is very strange that these gifts have developed simultaneously, for the greatest benefit of the primates that we are. ”
The findings of Albert Perry's Y chromosome study resonate with the work of Doctor of Genetics Georgia Purdom, who affirmed the existence of an original couple, ascendant of all mankind, as written in Genesis.
To date, the evolution of living things is far from having revealed all its secrets. The laminin, this protein that allows all cells to hold together, is a crucial part of understanding cancer development, may be part of the equation.
