back to article Boffins: We have found a way to unlock the MYSTERIES OF SHEEP from old parchments

Top-level boffins say they have discovered a valuable new tool for mapping the genetic history of sheep: namely, the extraction of DNA from old documents, which are generally written on parchment made from the skin of sheep or other animals. It seems that before such modern innovations as mass production of paper, typewriters …

    As these parchments have been handled by umpteen humans how do the boffins avoid contamination of the DNA?

    Or maybe the sheep were already contaminated :(

    I'll get my coat, it's the sheepskin one.

      DNA from different species is different. That's how it's possible to tell that your beef lasagne contains horse.

        Lends a whole new layer to the term "trigger foods".

      If they're legal documents they'll have been handled by lawyers and hence wouldn't be contaminated with Human DNA.

    Well obviously

    If the document is a legal one, it is very likely the DNA makes more captivating reading

    The effect is even more pronounced in the case of accountancy

    Large samples....

    You'd need a really large and comprehensive sample to piece pedigrees together..

    Parchment was both locally produced, but also heavily traded across well.. the world. Many pieces of parchment were also recycled (scraped) , bound, rebound, cut up, etc. The stuff ended up all over the place, so you'd need to do quite a bit of sampling to get a comprehensive picture, and prevent tagging, say, italian sheep as a british breed.

    Still, impressive work.

    Kudos to Proc. Roy. Soc. for not hiding behind a paywall.

      Seconded.

    Could be a problem...

    If they need to extract from the middle of the document, leaving a great hole - as in the example :D

    Bah.

    Excuse me (clears throat) Baa-a-a-a-aaa.

    Zzzz...

    A great idea.

    But am I the only one to feel that reading the family histories of sheep would have a similar effect to counting the sheep? Even the short paragraph about Swaledales and Scottish Blackface is venturing into the "more than you ever wanted to know about sheep" zone.

    Holy Cow

    This analysis will obviously be biassed towards breeds that produce good parchment.

    Where you have breeds that are good eatin' but the parchment is crap, they won't be well-represented. Similarly where you have extensive use of barbed wire, you get (more) holes in the sheep, and therefore in the parchment, and it's useless.

    (This is why they keep the cows for Bentley leather in fields without barbed wire...)

    Otherwise a great idea - but they can't have my deeds.

    Anthropodermic bibliopegy

    Anthropodermic bibliopegy was the practice of binding the trial notes of a murder with the skin off the back of the murderer. So once they are bored with sheep, there is another weird source for research.

      Thank you!

      I must save that to throw casually into a conversation sometime.

    The Test of Time

    After all, parchment was the writing material of choice for thousands of years, going back to the Dead Sea Scrolls.

    And it lasts thousands of years, not like modern paper which yellows in months, and degrades in a matter of years.

      Re: The Test of Time

      Yeah, well, they were writin' more important stuff on it back then, weren't they?

      You really think anyone is going to want to read your boss's emails in a thousand years?

      (well, maybe they would, if only for the comic value)

    Bah!

    "Legal documents".

    Would those be ancient Law Degree Certificates?

    And for an encore

    analyse the ink to determine the true history of squid.

      Re: And for an encore

      +1 for the joke, but I think historic ink was more likely made from iron and oak galls than squid.

      Re: And for an encore

      Also I'm not convinced you'll get any DNA from squid ink, what with it being a secretion which does not generally contain nucleated cells.
