R1a1 appears to be 11K (9000 BCE). R1b would have been slightly before (16K?) and probably represents Celtic-Italic-Germanic.
Basque along with lemnian, pelasgian, etc.. would be the paleo languages of europe and would correspond with paleogroup I. R1b is not the initial paleo settlement, it is a phylogenetically later group.
