The existence of an especially strong genetic association between the Irish and the Basques, one even closer than the relationship between other west Europeans, was first challenged in 2005, and in 2007 scientists began looking at the possibility of a more recent Mesolithic- or even Neolithic-era entrance of R1b into Europe. A new study published in 2010 by Balaresque et al. implies either a Mesolithic- or Neolithic- (not Paleolithic-) era entrance of R1b into Europe. However, all these genetic studies agree that the Irish and Basque (along with the Welsh) share the highest percentage of R1b populations. A recent whole genome analysis of 1 neolithic and 3 Bronze Age skeletal remains in Ireland suggested that the original farming population was mostly similar to present-day Sardinians, and the 3 Bronze Age remains had a Steppe component to their genetics showing links with Eastern Europe. Most modern Irish share more DNA with the 3 Bronze Age men from Rathlin than with the earlier Ballynahatty neolithic woman.
