DNA from Stone Age woman obtained 6,000 years on

https://www.bbc.co.uk/news/science-environment-50809586



This is the face of a woman who lived 6,000 years ago in Scandinavia.

Thanks to the tooth marks she left in ancient "chewing gum", scientists were able to obtain DNA, which they used to decipher her genetic code. This is the first time an entire ancient human genome has been extracted from anything other than human bone, said the researchers.

Dr Hannes Schroeder from the University of Copenhagen said the "chewing gum" - actually tar from a tree - is a very valuable source of ancient DNA, especially for time periods where we have no human remains.

"It is amazing to have gotten a complete ancient human genome from anything other than bone,'' he said.

What do we know about her?

She was genetically more closely related to hunter-gatherers from mainland Europe than to those who lived in central Scandinavia at the time and was likely descended from a population of settlers that moved up from western Europe after the glaciers retreated.
An amazing achievement .....

Yeah right....as well as chewing gum they found that her thumbs were overdeveloped from texting and they found a selfie on her phone....

Wow! She was pretty too. Looks young to die, unless she lived longer & the DNA was before she went.

Isn't modern technology amazing . To think in 50 years time what will it be like , what other amazing things will be discovered.

Wonder if they will find one of us in 6,000 years time?

Birch pitch - example

Lola lived on an island in the Baltic Sea around 3,700 B.C. She was lactose intolerant and may have suffered from gum disease, and she had recently dined on a meal that included ducks and hazelnuts.

What we can’t know about the individual researchers call Lola, however, is how long she lived—or even when or where she died—because all that’s known about Lola comes from DNA captured in a small wad of tree pitch that she chewed on and spat out some 5,700 years ago.

Birch pitch (also called tar), a glue-like substance made by heating birch bark, has been used to fasten stone blades to handles in Europe since at least the Middle Pleistocene (approximately 750,000 to 125,000 years ago). Blobs of pitch imprinted with human teeth marks have been found at ancient toolmaking sites, where archaeologists surmise the pitch was chewed to soften before use. Due to the antiseptic nature of birch bark, it may have also had medicinal properties.

Re: DNA from Stone Age woman obtained 6,000 years on

She and I went to school together, however, she was a grade ahead of me. The "gum" was originally attached to the bottom of her desktop.

I find this kind of science fascinating, although, I think they cheapen it a bit with the artists concept of what she may have looked like. If the evidence says she had blue eyes, and dark hair, so be it, but the rendering is tacky. I do understand that pictures sell, otherwise, the Republicans would not be able to share in the story.

What about the ducks and the hazelnuts .....
