Celtic social club in England was female - focused 2,000 class ago , a genetic study of Iron Age skeletons reveals . DNAanalysis of dozens of ancient burials uncovered a community whose lineage could be traced back to one woman , and testify that man conjoin the group upon marriage .
" This is the first time this type of system has been document in European prehistory , " study lead authorLara Cassidy , a human geneticist at Trinity College Dublin , read in astatement , " and it predicts female societal and political authorisation . It ’s comparatively uncommon in modern societies , but this might not always have been the case . "
An archaeologist excavates an Iron Age Celtic burial at Winterborne Kingston in Dorset, U.K.
Cassidy and her team analyzed the genomes of 57 people who were inhume in cemeteries in Dorset , a county in southwest England , to enquire the social body structure of the Durotriges , aCeltic tribethat reside the coast between 100 B.C. and A.D. 100 . Their study was put out Wednesday ( Jan. 15 ) in the journalNature .
Historically , little is known about the pre - Romanpeople of Britain , althoughJulius Caesarwrote about the Iceni clan , which was afterwards rule byBoudica , and noted that Gaelic women were allowed to tie multiple men . But archeological grounds from Celtic graves has long suggested that women were buried with prestigious item , suggest at their high position .
To figure out who was buried in the Dorset cemeteries , the researcher first sequence the buried individuals ' genome . They discovered that 85 % of the people were related to one another . to boot , more than two - thirds of these relatives shared a rare mitochondrial desoxyribonucleic acid lineage — U5b1 — and Ychromosomediversity was gamy , think of most the great unwashed had the same maternal ancestors but not the same paternal ones .
An Iron Age Celtic woman from Langton Herring, U.K., was buried with a mirror and jewelry.

" The U5b1 haplogroup has an ancient tie-up with Europe and Britain , " Cassidy told Live Science in an e-mail , but " the few modern individuals who belong to this haplotype are not necessarily direct posterity of women who know in this community . "
Further investigation of the genomic data point allowed the research squad to generate a syndicate Sir Herbert Beerbohm Tree that began with one founding woman and her four girl and traverse at least two centuries and several generation . give that most of the family members who did not share the same mitochondrial DNA were virile , they suspected valet were marrying into this community .
" Using genetical data point , we found multiple relative incidence of father , " Cassidy tell Live Science in an email , " one of whom had two adult daughters with the same mother . It is highly probable these person were considered husband to women in the community of interests . "
Because the partners they found show no grounds of recent relatedness , the investigator suggested in the subject that these Celt " had a deep knowledge of their own genealogies , which may have been used to guide marital arrangements among a kitty of related grouping in the local realm . "
Additionally , the research worker canvas previously published genetical data from over 150 archaeological sites across Europe . They found that the British Iron Age was unequaled in have low-pitched mitochondrial genetic diversity and high Y chromosome diversity , mean that Gaelic groups all over Britain were belike organized around authoritative maternal lineages .
Tom Booth , a bioarchaeologist at the Francis Crick Institute in London who was not involved in the subject field , tell Live Science in an email that this bailiwick is " one of the most compelling example of how archaeogenetics is mature , " as it focuses on the chronicle of a specific ancient residential area .

" We should be conservative when interpreting patterns of transmissible relatedness in ancient cemeteries , " Booth read , since " we can not be sure something equivalent to marriage as we understand it exist in Iron Age societies in Britain " and should not assume that people who were buried together lived together .
Nevertheless , the study has " pretty exquisite detail on how maternal kinship were often pre - eminent in determine who ended up in particular Durotriges cemeteries , " Booth say , and the psychoanalysis " allows us to glimpse them much more on their own terminus rather than through a Roman lens . "
That lens appears to have been distaff - concentrate , which resonates with Roman descriptions of Celtic women . The researcher conclude in their work that " although classic depictions of conquered hoi polloi are often reckon with scepticism , we find here some truth in these writers ' estimation of Iron Age Britain .
