Are Paracas Elongated Skulls a New Species, Aliens or a Hoax?

Initial DNA analysis of one of the 3,000-year-old elongated skulls found in Paracas, Peru, has revealed that they may not have been come from humans but from a completely new species, according to Paracas Museum assistant director Brien Foerster.

Foerster, who also runs his own tour group company in Peru and has authored 11 books on ancient history, told Ancient Origins that a geneticist who tested skull samples has found that they contain mutated DNA that does not match any known genetic DNA information in GenBank, an open-access sequence database of all the known genetic data in the world.

The unidentified geneticist told Foerster: “It had mtDNA (mitochondrial DNA) with mutations unknown in any human, primate, or animal known so far. But a few fragments I was able to sequence from this sample indicate that if these mutations will hold we are dealing with a new human-like creature, very distant from Homo sapiens, Neanderthals and Denisovans.”

“I am not sure it will even fit into the known evolutionary tree,” the geneticist added.

Geneticist won’t come forward, for now

According to Foerster, the geneticist in question, who apparently does contract work for the US government, is willing to go public, but does not want to come forward until the tests prove the theory conclusively.

Peruvian archaeologist Julio Tello discovered the skulls in 1928 in a massive graveyard in Paracas, desert peninsula in the Pisco Province on the south coast of Peru. Over 300 skulls were discovered and are some of the largest elongated skulls to have been found in the world.

Generation of ‘X-Men’ superhumans could become a reality in 30 years thanks to advances in gene science, say MoD experts

  • Experts warn of ‘genetic inequality’ if advances are unequally shared
  • Report says ‘human augmentation’ is likely to increase over next 30 years
  • Details released following a Freedom of Information request
A generation of genetically-modified ‘X-Men’ superhumans could be among us by 2045, a Ministry of Defence think tank has said.Advancements in gene technology could help humans gain mutant powers such as the likes of Wolverine, Cyclops and Storm in the popular comic book and movie series, it has been reported.

The MoD’s Development Concepts and Doctrine Centre warn however that ‘genetic inequality’ could result from advancements in biology being unequally shared across society.

Mutant: MoD experts have suggested a generation of genetically-modified ‘X-Men’ superhumans, such as Wolverine, could be a reality by 2045

The centre met last summer for a two-day summit, featuring experts from government, industry and universities. The details have been released following a Freedom of Information request by The Sun.

It was reported during the summit, held to predict what would happen in the future, that: ‘Advancements in gene technology could lead to a class of genetically superior humans by 2045.

‘Human augmentation is likely to increase over the next 30 years.

‘Discussions highlighted that it is possible that advances in biology, unequally shared across society, could generate genetic inequality.’

The X-Men are a team of mutant superheroes created by writer Stan Lee and artist Jack Kirby, who first appeared in Marvel Comics in 1963.

The mutants use their powers for the benefit of humanity, despite an ever-growing anti-mutant sentiment among mankind.

The comics were turned into a highly-successful film series, featuring Hugh Jackman as Wolverine, Halle Berry as Storm, Ian McKellan as Magneto and Patrick Stewart as Professor X.

Were Neanderthals Part Human?

Folks residing outside the house Africa discuss as significantly as several for each cent of their DNA with Neanderthals, a cave-dwelling species with muscular small arms and legs and a mind marginally larger than ours.

The Cambridge scientists examined demographic styles suggesting that human beings were far from intimate with the species they displaced in Europe nearly forty,000 many years in the past.

The research into the genomes of the two species, located a frequent ancestor five hundred,000 many years in the past would be adequate to account for the shared DNA.

Their assessment, revealed in the journal Proceedings of the National Academy of Sciences (PNAS), contradicts latest reports that discovered inter-species mating, identified as hybridisation, almost certainly transpired.

Dr Andrea Manica, who led the review, said: “To me the interbreeding question is not whether there was hybridisation but whether there was any hybridisation that afflicted the subsequent evolution of individuals. I assume this is really, quite not likely.

“Our work shows clearly the patterns presently witnessed in the Neanderthal genome are not outstanding, and are in line with our expectations of what we would see with no hybridisation.

“So, if any hybridisation happened then it would have been minimum and considerably less than what individuals are proclaiming now.”

Data has shown that Neanderthals ended up pushed into extinction by humans who have been a lot more efficient at obtaining food and multiplied at a more quickly fee.

A prior review in 2010 suggested that interspecies liaisons near the Middle East resulted in Neanderthal genes initial moving into humans 70,000 a long time in the past.

Contemporary non-Africans reveal more with Neanderthals than Africans, supporting the claim that the mixing happened when the initial earlier humans remaining Africa to populate Europe and Asia.

The existence of a five hundred,000-12 months-old shared ancestor that predates the source of Neanderthals gives a greater rationalization for the genetic mix.

Variety inside this ancestral species intended that northern Africans have been far more genetically similar to their European counterparts than southern Africans through geographic proximity.

This likeness persisted above time to account for the overlap with the Neanderthal genome we see in modern people these days.

Variations in between populations can be described by prevalent ancestry, Dr Manica said.

“The notion is that our African ancestors would not have been a homogeneous, effectively-mixed populace but manufactured of a number of populations in Africa with some degree of differentiation, in the way proper now you can explain to a northern and southern European from their appears,” she mentioned.

“Based on common ancestry and geographic differences amid populations inside of every single continent, we would forecast out of Africa populations to be far more comparable to Neanderthals than their African counterparts – just the patterns that ended up observed when the Neanderthal genome was sequenced, but this routine was attributed to hybridisation.

“Ideally, every person will turn out to be far more careful just before invoking hybridisation, and start off having into account that historic populations differed from every other almost certainly as significantly as present day populations do.”

Northern Africans would be far more comparable to Europeans and ancient similarity stayed due to the fact there wasn’t ample mixing among northern and southern Africans.

Populace diversity, known as substructure, cant make clear info on the shared genes, mentioned David Reich, a professor of genetics at Harvard Health-related College, in Boston who authored the 2010 examine.

We have ruled out the chance that historical substructure can make clear all the proof of higher relatedness of Neanderthals to non-Africans than to Africans, he extra.

Dr Manica stated hybridisation among Neanderthals and people can never ever be disproved completely.

What is the Human Genome

Here is the definition taken from the Human Genome Project, “A genome is the complete collection of an organism’s genetic material. The human genome is ”"composed of about 20,000 to 25,000 genes located on the 23 pairs of chromosomes in a human cell.

A single human chromosome may contain more than 250 million DNA base pairs, and scientists estimate that the entire human genome consists of about 3 billion base pairs.

In the past eighteen months, scientists discovered more than 100 genetic variations that affect older people, such as: type 2 diabetes, asthma, Alzheimer’s disease, osteoporosis, high blood pressure and heart disease.

Genetic science is moving so fast that people now in their 60′s-80′s will see medical innovations that will touch their lives.

Francis Collins, MD, a leader in the Project, was astounded to see the huge amount of information derived from the genome, particularly in regards to older people.

As an example he cited age-related Macular degeneration, an eye disease troubling almost 2 million, visually impaired Americans. “Using new genomic tools we’ve discovered two genes that account for about 60% of the risk- the rest is smoking. But we were surprised. These genes are involved in inflammation, and everybody was thinking macular degeneration was caused by aging in the back of the eye.”

Macular degeneration tests are now being made using anti-inflammatory drugs, a complete change in the way it was formerly viewed.

Many scientists believe that the Human Genome Project has the potential to revolutionize both therapeutic and preventive medicine by providing insights into the basic biochemical processes that underlie many human diseases.
