The Dead Sea Scrolls contain genetic clues to their origins

Genetic clues extracted from slivers of the well-known Dead Sea
Scrolls are serving to to piece collectively associated scroll remnants and reveal the
numerous origins of those historical texts, together with a ebook of the Hebrew Bible.

The scrolls are made from sheepskin and cow pores and skin, which retain
DNA from these animals. Analyzing that DNA represents a brand new method to determine
which of the greater than 25,000 Dead Sea Scroll fragments come from the identical animals,
and thus seemingly the identical paperwork, say molecular biologist Oded Rechavi of Tel
Aviv College and his colleagues.

Findings to date recommend that the Dead Sea
Scrolls reflect religious and biblical developments across southern Israel

round 2,000 years in the past, not simply amongst individuals who lived close to the caves the place many
scrolls have been saved, as some students have contended, Rechavi’s staff reviews
June 2 in Cell.

Researchers estimate that the Dead Sea Scrolls have been written between the third century B.C. and the primary century A.D., throughout what’s referred to as the late Second Temple interval. That was a essential time within the improvement of Judaism and the emergence of Christianity. “Our outcomes show the heterogeneity inherent in Second Temple Judaism, which shaped the matrix for [early] Christianity,” says Tel Aviv College Biblical scholar and research coauthor Noam Mizrahi.

The Dead Sea Scrolls include about 1,000 historical
manuscripts, together with the earliest recognized variations of books of the Hebrew Bible
and non-biblical spiritual, authorized and philosophical paperwork. Most scrolls and
scroll fragments have been discovered between 1947 and the 1960s. The largest set of
finds comes from 11 caves close to Qumran, a web site positioned within the Judean desert on
the Dead Sea’s northwest shore.

Many researchers have surmised that scrolls from the Qumran
caves mirror the beliefs of a
small Jewish sect that broke from mainstream Judaism
and settled in Qumran
(SN: 11/17/17). However DNA proof within the new research means that concepts in
these paperwork additionally prolonged past the Qumran group.

Rechavi’s group obtained DNA from minuscule bits that both
fell off or have been faraway from 26 Dead Sea Scroll fragments. These samples
contained no writing.

After excluding DNA left by individuals who had dealt with the
scrolls, the scientists recognized DNA of animals used to make the traditional parchments.
All fragments have been made from sheepskin besides for 2 constructed from cow pores and skin.

Comparisons of mitochondrial DNA, usually inherited from
the mom, and nuclear DNA, inherited from each mother and father, enabled the
researchers to establish shut or distant relationships amongst sheep used to make
the scroll fragments. The researchers assumed that fragments from intently
associated sheep have been extra seemingly to come from the identical doc than these from
distantly associated sheep or from cows.

Research of the texts had beforehand prompt that many
Qumran scrolls show spellings and different options of a writing custom
specific to a small group of scribes, and the genetic proof helps that
proposal. Seven of eight fragments containing writing beforehand classed as
a part of that “Qumran scribal apply” got here from intently associated sheep,
suggesting that these fragments symbolize manuscripts that had originated in
the identical place.

“For the primary time, this concept [of a Qumran scribal
practice] has been supported by impartial historical DNA analysis,” says
Biblical scholar and linguist Emanuel Tov of Hebrew College of Jerusalem.
Tov is previous editor in chief of what’s now the Dead Sea Scrolls Digital Project.

4 Qumran fragments from the Hebrew Bible’s ebook of
Jeremiah seemingly got here from two completely different variations of that ebook, the
investigators discover. Two sheepskin fragments belonged to one ebook and two cow
pores and skin fragments belonged to one other. Cows couldn’t have been raised within the
parched Judean desert, so cow pores and skin scrolls should have been produced elsewhere,
Mizrahi says.

Students had already famous that the fashion of writing on the
cow fragments differed from that on different items from the ebook of Jeremiah.

DNA findings additionally point out {that a} non-biblical textual content about
spiritual practices referred to as the Songs of the Sabbath Sacrifice was widespread past
Qumran. Fragments from three copies of this textual content present in two Qumran caves have been
constructed from skins of intently associated sheep. However a fraction from one other copy
discovered at Masada, about 55 kilometers south of Qumran, got here from a genetically
separate line of sheep, suggesting that folks there assembled their personal copy
of the textual content.

Distinctive sheep DNA from a Qumran fragment of the biblical
ebook of Isaiah suggests it got here from exterior Qumran at a web site that’s but to be
recognized.
