Ancient DNA on parchments reveal hidden stories

Print

Parchment documents--ancient writings on animal skins--record an immense wealth of information about the history of humanity and past civilizations. However, new research has shown that within these ancient texts lies another hidden source of knowledge – the DNA preserved in the animal skins used to make the parchment.

The main species used for documents recorded on animal skins, which dates back to around 2,500 BC in Egypt, were young or fetal cattle, sheep and goats. Parchment was used for writing mercantile, legal, scholarly, religious, philosophical and historical documents.

Aside from their human historical value, DNA in parchments may help scientists understand the genetic history of domesticated farm animals. Scientists from the University of York in England and Trinity College in Ireland hope to use DNA from parchments to study the history of agriculture in the British Isles over the past 1,000 years.

As a pilot study, they extracted DNA samples from two sheepskin documents in Britain – one from the 17 th century, the other from the 18 th century. Daniel Bradley, a professor of Population Genetics Trinity College Dublin told the university’s news service: “This pilot project suggests that parchments are an amazing resource for genetic studies that consider agricultural development over the centuries. There must be millions stored away in libraries, archives, solicitors’ offices and even in our own attics. After all, parchment was the writing material of choice for thousands of years, going back to the Dead Sea Scrolls (5 th – 4 th century BC).

“Wool was essentially the oil of times gone by, so knowing how human change affected the genetics of sheep through the ages can tell us a huge amount about how agricultural practices evolved.” 

The DNA extracted from these parchments revealed that the 17 th century sample came from sheep from Northern Britain, where there were Swaledale, Rough Fell and Scottish Blackface sheep. The second DNA sample showed a closer connection to the Midlands and southern Britain, where livestock improvements were underway in the 18 th century.

Professor Matthew Collins, head of the University of York’s Department of Archaeology’s  BioArCh research center, said: “We believe the two specimens derive from an unimproved northern hill-sheep typical in Yorkshire in the 17th century, and from a sheep derived from the ‘improved’ flocks, such as those bred in the Midlands by Robert Bakewell, which were spreading through England in the 18th century. We want to understand the history of agriculture in these islands over the last 1,000 years and, with this breath-taking resource, we can.”

Writing in The Royal Society Publishing, the researchers estimated there could be 4 million or more ancient parchments in Britain alone because the primary method of inscribing was on parchment until paper replaced parchment in the later Middle Ages, around the 15 th century. Many parchment documents were protected from heat and moisture damage in the 20 th century.

“Indeed, the number of skins is truly staggering, even if, as is likely, a high percentage of documents have been destroyed. In the UK alone, assuming the number of sheep slaughtered annually remained constant at 15 million from 1150 to 1850, then if only 1% of all the skins became parchment and only 4% survived, this would equate to 4.2 million animals' skins,” the researchers wrote. They say it is hard to estimate the number but believe more than 1 million survive.

Parchments can be dated fairly precisely using modern methods, which is valuable in assessing the genetic changes in animals through time.

Humans did no exist before 1850 AD, the word human can't be found in the US Constitution or the Bible.
Let alone umpteen years ago, it might be mankind, certainly not humankind. Look up the origin of the word human. QED

...the Billy Meier site, www.theyfly.com and book.. The Pleiadian Mission by US psychologist Randolph Winters, based on the Meier's 70 years plus, still ongoing et contacts. Many here share common ancestry with this race, as we descended from an ancient race from the Lyra Constelaltion, sun Vega. This group of et are now 12,500 years ahead of us in tech, medicine and knowledge The Creational Laws. They have given us our 22 million year history on Planet Earth since they/some of us first visited from Lyra.

They live 500 light years distant in the Taurus Constellation, sun Taygeta, on 4 inhabited planets, in a slightly different 'time'. They take 7 hours to get here in their own ships, but have a new ship on loan from friends in the Dal parallel Universe that gets here in a millionth of a second. The Dals also gave them the tech for their 'big spacer', that is 10 miles in diameter with a crew of 144K and fully self contained.

If you believe that 4M years ago your ancestors were chimps, when humankind in this Dern Universe has a history of nearly 100 billion years, in this Great Time, a Great Time being 311.04 trillion years, and that maybe we learn our history from parchment DNA.... that's your problem.
