Scientists Agree: Younger Dryas Impact Event Wiped Out Ancient Civilization | Ancient Architects
QuoteDisplay MoreThe Earth was hit by a fragmented comet around 13,000 years ago at the end of the Pleistocene Era and scientists are now starting to agree.
A new research paper has been published in Scientific Reports regarding an ancient civilisation in what is modern-day Syria that was wiped out by the cataclysm, as academics finally come round to the idea that yes this event did happen.
Even the sceptic Michael Shermer, who famously debated Graham Hancock on the Joe Rogan podcast has tweeted Graham saying:
“Ok Graham, I shall adjust my priors in light of more research like this, and modify my credence about your theory.”
The evidence always spoke for itself for a lot of people, but it’s positive to see him address Graham in a public manner like this.
So what have the scientists discovered? Well, remnants of glass have been found that could only have been created during a high-impact event. Other minerals such as chromium, iron, nickel and others were discovered too, all of which form at temperatures higher than 2,200 degrees, according to a statement from the University of California-Santa Barbara.
The site the discovery was made is known as Abu Hureyra, which was abandoned around 5,000 years ago.
The glass finds are believed to have been formed from the instantaneous melting and vaporization of regional biomass, soils and floodplain deposits, followed by instantaneous cooling. This is really only common during impact events.
Graham Hancock and others such as Randall Carlson have long said that it was likely a fragmented comet, and that is what the scientists are saying who are analysing the Syrian finds. A single, major asteroid impact could not have caused the widely scattered material discovered at Abu Hureyra and the experts say that it is more likely a fragmented comet.
The Younger Dryas Event is what caused a large megafaunal extinction, seeing the end of woolly mammoths, species of bison, American horses and camels, and giant sloths. It also saw the end of the North American Clovis culture.
The evidence is there in the field and it continues to stack up. Two years ago we read about reports of a 19-mile wide crater in Greenland that could be related to this cataclysmic event and in October 2019, a study was published that said there was a mini ice age 12,800 years ago that was caused by an impact event.
But at the beginning of this mini ice age there were huge levels of burning and now we know that Abu Hureyra was abruptly destroyed from what can only be an impact event. We have new direct evidence of the disaster, together with tons of data from around the world. History is finally being re-written!
Neanderthals ate sharks and dolphins By Paul Rincon

Neanderthals were eating fish, mussels and seals at a site in present-day Portugal, according to a new study.
The research adds to mounting evidence that our evolutionary relatives may have relied on the sea for food just as much as ancient modern humans.
For decades, the ability to gather food from the sea and from rivers was seen as something unique to our own species.
Scientists found evidence for an intensive reliance on seafood at a Neanderthal site in southern Portugal.
Neanderthals living between 106,000 and 86,000 years ago at the cave of Figueira Brava near Setubal were eating mussels, crab, fish - including sharks, eels and sea bream - seabirds, dolphins and seals.
The research team, led by Dr João Zilhão from the University of Barcelona, Spain, found that marine food made up about 50% of the diet of the Figueira Brava Neanderthals. The other half came from terrestrial animals, such as deer, goats, horses, aurochs (ancient wild cattle) and tortoises.
Brain-boosters?
Some of the earliest known evidence for the exploitation of marine resources by modern humans (Homo sapiens) dates to around 160,000 years ago in southern Africa.
A few researchers previously proposed a theory that the brain-boosting fatty acids seafood contributed to enhanced cognitive development in early modern humans.
This, the theory goes, could help account for a period of marked invention and creativity that started among modern human populations in Africa around 200,000 years ago. It might also have assisted modern humans to outcompete other human groups such as the Neanderthals and Denisovans.

ASTRONAUTS GROWING NEW ORGANS ON INTERNATIONAL SPACE STATION
QuoteDisplay MoreAstronauts are growing the beginnings of new organs on board the International Space Station.
The experiment is an attempt to grow human tissue by sending adult human stem cells into space, and allowing them to grow in space.
Eventually, it is hoped, the stem cells will develop into bone, cartilage and other organs. If that is successful, the discoveries could be used to try and grow organs for transplant, the scientists involved say.
The experiment uses “weightlessness as a tool”, according to Cara Thiel, one of the two researchers from the University of Zurich who are conducting the research. The lack of gravity on board the International Space Station will be used to encourage the stem cells to grow into tissue in three dimensions, rather than the single-layer structures that form on Earth.
It is being conducted by the astronauts on board the International Space Station using a “mobile mini-laboratory” that was sent on a SpaceX rocket last week. The experiment will last for a month, during which scientists will watch to see how the stem cells grow.
If it is successful, they hope to switch from a small laboratory to bigger production. From there, they could use the process to generate tissue for transplants by taking cells from patients, or generating organ-like material that could be used to test drugs, either ensuring that it works for a specific patients or reducing the number of animals used in experiments.
On Earth, tissue grows in “monolayer” cultures: generating flat, 2D tissue. But investigations both in space and Earth suggest that in microgravity, “cells exhibit spatially unrestricted growth and assemble into complex 3D aggregates”, said Oliver Ullrich, who is also leading the research.
Previous research has involved simulated ad real experiments, mostly using tumour cells, and placing real human stem cells into microgravity simulators. But for the next stage of the research “there is no alternative to the ISS”, he says, because 3D tissue formation of this kind requires several days or even weeks in microgravity.
After the month-long experiment, the scientists will get the samples back and expect to see successful formation of ”organoids” – smaller, more simple versions of organs – inside the test tubes. “The test tubes were launched with stem cells and are expected to return to Earth with organ-like tissue structures inside,” said Professor Ullrich.
Scientists are still not sure why the conditions of the International Space Station lead to the assembly of complex 3D tissue structures. Professor Ullrich and other scientists are still continuing to research how the gravitational force and the “molecular machinery in the cell” interact to create new and different kinds of tissue on Earth and in space.
