Hunting for DNA in Doggerland, an Ancient Land Beneath the North Sea

http://www.wired.com/2015/11/hunting-for-dna-in-doggerland-an-ancient-land-beneath-the-north-sea/



...Archaeologists began looking at remote sensing data that these companies had gathered while seeking oil and gas. They had a 3D seismic dataset that shows distinct layers. “Imagine just cutting a nice big cake,” Gaffney says. “You can see the layers of sponge and cream—and of course on the bottom there’s oil in there somewhere.” The energy companies only care about the very bottom of the cake, but Gaffney and his colleagues focused on a layer closer to the frosting. Based on studies that had dated the sediment, they knew that between 30 and 50 meters under the sea floor lay the former surface of Doggerland.

Tracing this layer of sediment, the team mapped about 17,000 square miles of the drowned and buried country—an area, Gaffney says, “slightly larger than Holland.” In its topography they’ve found hills, coastlines, lakes and rivers. “But it’s a map without people at the moment, or animals or plants,” Gaffney says. That’s where the project’s next phase comes in.

The European Research Council recently awarded a team led by Gaffney a €2.5 million grant—about $2.6 million. Soon the scientists will head to sea. But they plan to do a lot more than just make maps. They’ll follow two of the country’s sunken river beds, taking core samples in search of pollen, fossils, insect remains, and other signs of life.

They’ll also hunt for ancient DNA. This technique is still new and somewhat controversial. In a paper in the journal Science last February, members of the same team described DNA they’d dug up at Bouldnor Cliff, a submerged site off the Isle of Wight. They found evidence of wheat from 8,000 years ago—about 2,000 years before farming arrived in mainland Britain. Other researchers argued that the wheat DNA must have been modern contamination. In the Doggerland samples, the team will look for DNA from crops or even domestic animals like sheep and goats. Gaffney says the findings might help identify the best spots to search for human archaeology—evidence of cleared areas, burning, or environments that would have made ideal settlements.

The samples will cover about 5,000 years of Doggerland’s history, from around 10,000 BC until the sea swallowed it...

3. What's interesting with this timeline map is recent findings

The Ness of Brodgar archaeological site in the Orkney Islands is almost a thousand years older than Stonehenge and the center for Neolithic Britain and shares some of the same cultural artifacts found there.

Now if we look at your map you can see that these islands in Northern Scotland were once mountain regions of early Doggerland that was first area destroyed by the first stage of the flooding in the timeline. In fact the earliest record of Neolithic Britain are all almost found in Scotland with some exceptions.

If you notice in your map the largest major river system in Doggerland is east of the Orkney's which would be a desirable place for human settlement.
Suggesting that the Orkney mountains is where they fled to during the flood.








And this is the location of after flood settlements and Ness of Brodgar plus
The Ring of Brodgar which The site has resisted attempts at scientific dating and the monument's age remains uncertain.





Ring of Brodgar much older than Stonehenge

I think that a underwater study of that flooded river system would be interesting.

4. Desirable land, yes, and with an early

 

human population with an astronomically numerate culture, as you point out...

Of interest, indeed.

5. Notice the majority of Megalithic Sites are on the east coast

the bright orange areas on the map have numerous sites

Notice no sites where that ice sheet was in Scotland.


Look how Scotland fares



You can explore the map and the sites here they break down each grid into sites in the area

8. Comet Collided With Earth 13,000 Years Ago and help melt the ice sheets

New evidence supports the idea that a huge space rock collided with our planet about 13,000 years ago and broke up in Earth's atmosphere, a new study suggests.

This impact would have been powerful enough to melt the ground, and could have killed off many large mammals and humans. It may even have set off a period of unusual cold called the Younger Dryas that began at that time, researchers say.

The idea that Earth experienced an asteroid or comet impact at the start of the Younger Dryas has been controversial, in part because there is no smoking-gun impact crater left behind as with other known events in our planet's past. But researchers say it's common for space rocks to disintegrate in the heat of a planet's atmosphere before they can reach the ground.

The scientists first reported their suspicions about the event in 2007. Now, they say, a new site in Central Mexico's Lake Cuitzeo displays telltale signs of an impact, including melted rock formations called spherules and microscopic diamonds that could only have formed under extreme temperatures.

The researchers, led by Isabel Israde-Alcántara of Mexico's Universidad Michoacana de San Nicólas de Hidalgo, published their findings online March 5 in the journal Proceedings of the National Academy of Sciences.
