I know they only have 20% R1b; they are not Celtic. They are dominated by hg I-M26, the Sardinian I variety, at 45% or nearly 1 out of ever 2 men. They also have about 15-20% E3b and G, with very low levels of J. They do not cluster with Iberians; they are a global isolate. Sardinians are their own different component over all, they have the highes P15 (G2a) levels in Europe which settled in Sardinia ( responsible for Nuraghic civilization) and predominantly are an isolated hg I branch present outside of Sardinia nowhere even close as high as in Sardinia. They also have pockets of R1b and E3b at lower percentages; its not only that Sardinians don't cluster with other Italians, Corsicans or Sicilians. It's that they don't cluster with any other Europeans either mostly. The first Iberians had probably R1b and certain varieties of I that waited out the LGM. Outside of Sardinia, only central Spain ( Castile/Leon region) has very low but appreciable levels of I-M26, bringing me to believe it arrived in Sardinia via central Spain as one of the first elements to reach Sardinia along with the early but separate middle-eastern arriving G2a men.
