DNA Evidence Debunks the “Out-of-Africa” Theory of Human Evolution

DNA Evidence Debunks the “Out-of-Africa” Theory of Human Evolution

“Rebecca Cann was more expansive and specific in declaring that the Original “Mitochondrial DNA puts the origin of Homo Sapiens much further back and indicates that the Australian Aborigines arose 400,000 years ago from two distinct lineages, far earlier than any other racial group.” The notions of a “far earlier” time frame when estimating when, and the existence of “two lineages” in Australia when grappling with who, are constant themes that can be found within many other reports investigating the make up of the genes and chromosomes of Homo sapien sapiens.”

An article in the New York Times on 4th December 2013 lays claim to a “baffling 400,000 year old clue to human origins”. On this occasion, humanity’s indirect ancestry was traced back to Spain during pre-Homo sapien sapiens times, and once again Denisovan genes are at play. So it appears the same hominid who is most closely linked to the Original genes of Australia was wandering around the Spanish countryside some 400,000 years ago, well before any African Homo sapien could be claimed to have stepped in, on or outside African soil.

“Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding is adding new mysteries”. The femur bone found in cave was analysed by Dr. Matthias Meyer (geneticist Max Planck Institute for Evolutionary Anthropology). When Meyer and his colleagues “drilled into the femur, they found ancient human DNA inside, just as they hoped”.

But past this point, nothing went according to their script. Much to their surprise, the DNA they recovered – the oldest yet by over 100,000 years – “most closely resembles DNA from an enigmatic lineage of humans known as Denisovans”, originally thought to be 80,000 years old and confined to the Northern Asian region. This finding was the cause of great consternation. “Everyone had a hard time believing it at first” Dr. Meyer said. “So we generated more and more data to nail it down”. Not surprisingly, their further research only confirmed the original results.

As Meyer quite rightly observed: “right now, we’ve basically generated a big question mark”.
