Did you know Ireland has the highest concentration of men with the R1b DNA marker? No fewer than 84 per cent of all Irish men carry this on their Y chromosome....“The high prevalence rates have always perplexed Irish geneticists and historians,” says Alastair Moffat of IrelandsDNA. The firm’s research proposes a new hypothesis. There is already established evidence suggesting that the first farmers, (carrying the Y chromosome lineage of ‘G’, which can be found across Europe) arrived in Kerry about 4,350BC.According to IrelandsDNA, the so called ‘G-Men’ may have established farming in Ireland “but their successful culture was almost obliterated by what amounted to an invasion, even a genocide, some time around 2,500BC” (the frequency of G in Ireland is now only 1.5 per cent). “There’s a cemetery in Treille [France], where ancient DNA testing has been carried out and almost all men carry the ‘G’ marker but the women don’t,” says Moffat. They carry native/indigenous markers. This strongly suggests incoming groups of men. Because the R1b marker is still so prevalent in Ireland and is also frequently found in places like France and northern Spain we believed that around 2,500 BC, the R1b marker arrived in Ireland from the south.”...
