In November 2013, scientists extracted one of many world’s oldest human DNA from a 400,000-year-old femur, containing proof of an unknown species on earth. The DNA of those a whole lot of hundreds of years outdated human ancestors reveals a posh sample of evolution within the origins of Neanderthals and trendy people.
The bone belongs to a human, however accommodates “Extraterrestrial DNA”. This outstanding discovery has led scientists to query the whole lot they find out about human evolution.
The 400,000-year-old genetic materials comes from bones which were linked to Neanderthals in Spain, however its signature is most much like that of one other historic human inhabitants from Siberia generally known as the Denisovans.
Greater than 6,000 human fossils, representing some 28 people, have been recovered from the location of Sima de los Huesos, a hard-to-reach cave, at a depth of about 30 meters in northern Spain. The fossils appeared unusually well-preserved, thanks partially to the fixed cool temperature and excessive humidity within the pristine cave.
The skeleton from Sima de los Huesos Cave has been attributed to an early human species generally known as Homo heidelbergensis. Nevertheless, researchers say the skeletal construction is much like that of Neanderthals — a lot in order that some say the inhabitants of Sima de los Huesos have been truly Neanderthals, not Homo heidelbergensis.
The researchers who performed the evaluation stated their outcomes present an “sudden connection” between our two extinct associated species. This discovery might unravel the thriller — not only for the primary people who lived within the cave advanced generally known as the Sima de los Huesos (Spanish for “Pit of Bones”), but in addition for different enigmatic populations throughout the Pleistocene period.
Earlier evaluation of the bones from the cave led researchers to recommend that the Sima de los Huesos individuals have been intently associated to Neanderthals based mostly on their skeletal options. However the mitochondrial DNA was way more like that of the Denisovans, an early human inhabitants thought to have break up from the Neanderthals about 640,000 years in the past.
A 3rd sort of individuals, referred to as Denisovans, appears to have coexisted in Asia with Neanderthals and early trendy people. The final two are recognized from quite a few fossils and artifacts. Denisovans have up to now solely been recognized by DNA from one bone and two enamel, however this opens up a brand new twist in human historical past.
The scientists additionally discovered that 1 p.c of the Denisovan genome got here from one other enigmatic relative, which scientists have dubbed “superarchaic man.” In flip, it’s estimated that some trendy people could include about 15 p.c of those “superarchaic” gene areas. Thus, this examine reveals that the Sima de los Huesos individuals have been intently associated to Neanderthals, Denisovans, and an unknown inhabitants of early people.
Who may very well be this unknown ancestor of man?
One potential contender may very well be Homo erectus, an extinct human ancestor that lived in Africa about 1 million years in the past. The issue is, we’ve by no means discovered H. erectus DNA, so probably the most we are able to do proper now’s speculate.
Then again, some theorists have provide you with some actually intriguing hypotheses. They argue that the so-called 97 p.c of the non-coding sequences in human DNA are nothing greater than the genetic code of extraterrestrial life kinds.
Based on them, within the distant previous, human DNA was purposefully designed by some extremely developed extraterrestrial race; and the unknown “superarchaic” ancestor of the Sima de los Huesos individuals could also be proof of this synthetic evolution.
An extraterrestrial connection or an unknown human species, no matter it’s, the outcomes solely additional complicate the evolutionary historical past of contemporary people – maybe much more populations might have been concerned.
The solutions to our true historical past are hidden in our DNA all through our historical past, and it’s there that we should search for the origins of the human race.
