DNA Can Now be Extracted from Dirt! New Tech May Solve Many Mysteries of Human Origins
An amazing technological innovation in the study of DNA has been called a ‘game changer’ in the research into ancient humans and hominids. It may solve many of the mysteries that exist in relation to the origins of humans and could completely rewrite our family tree.
A new study published in the journal Science has revealed a technique that can extract human and hominid DNA from dirt – no bones needed! This means that by simply taking half a teaspoon of soil from a cave and running it through the new analysis, scientists will know if species of ancient hominids lived in that cave and who or what they were.
“This is pretty damn incredible,” said Rob Scott , an evolutionary anthropologist at Rutgers. Tom Higham, an Oxford professor who specializes in dating bones, called the discovery a “new era in Paleolithic archaeology.”

Scientists have known for over a decade that DNA, which may have come from urine, feces, sweat, blood, semen or a decomposed body, can survive in ancient sediments, even for hundreds of thousands of years, but they had no way to analyze it. Just a teaspoon of dirt can contain trillions of fragments of DNA from dozens of different species.
However, research from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, discovered that they could cut through the clutter with a molecular ‘hook’ made from the mitochondrial DNA of modern humans. This means that essentially, they were able to pull out the fragments of DNA that specifically belonged to a human or hominid species.
The scientific team collected 85 sediment samples from seven archeological sites in Belgium, Croatia, France, Russia and Spain, covering a span of time from 550,000 to 14,000 years ago. With the new method, they were able to capture DNA fragments from Neanderthals and Denisovans, an enigmatic human ancestor that so far has only been found in single cave in Russia. They even identified Neanderthal DNA in a cave in Belgium where no bones had ever been found.

“By isolating DNA directly from sediments, we can dramatically expand what we know about where people were, when they got there, and how long they stayed,” Beth Shapiro, an evolutionary biologist at the University of California, Santa Cruz, told ScienceMag.
It is expected that the new technique will now become a standard method of analysis in the field of archaeology, much like radiocarbon dating. The next step will be to examine archaeological sites that have stone tools but no evidence of who made them. Many mysteries can now be solved.
“It could also reveal even more hominid species that we have not found bones for,” reports SmithsonianMag, “creating an even more complete human family tree.”

BINGO !!! Genesis secret has been revealed. And God went through the arduous task of creating Adam from the dust of a meteor that struck the planet earth. Creating Eve was a much simple en-devour because Adam only had to donate his living flesh and bone (mother cells), to create Eve.
There is no mystery to human origins. The gods made us slave workers to mine gold for them.
The entire government are evil treasonous criminals! The day of the next false flag using the nuke the evil government stole in 2007 and blamed on Iran, America will be annihilated by Russia, China and the SCO. This is the war of Armageddon and you can know it is now because of Planet X and the toxic chemtrails that hide it every day globally for the past decade. Planet X will end the war when it rips the earth apart again but by then 90% of Americans will be dead already. All planned by your evil government and their evil alien masters!
no bones found, no remains found, yet, they claim they found DNA from "thousands of years ago". Something is TOTALLY wong. One guess is that these so-called "scientists" have their brains tottally smashed. Get the facts: even in the best conditions, the half-life of DNA is about 500 years; so in 3000 years there is virtually only very short fragments (READ: dinucleotides, tri-nucleotides, penta-nucleotides), so short that you could do watever ou waant with them: they can fit into the elephant genome, or the ant genome, or in the monkey genome, or the human genome, etc. In other words, they are just inventing. Remember the golden rule: NO BONES, then is IDIOTIC to look for DNA. Period.
