Whatever the reason, the haplogroup R1a1 virtually disappeared from the Europe at about 4,500-4,000 years ago, and the Türkic-speaking carriers of the haplogroup R1b colonized the deserted Europe. As is shown several lines below, virtually all modern branches of the haplogroup R1a1 in the Europe are dated from the 2,900-2,500 years ago and later. At the same time, there is evidence that haplogroup R1a1 was in Europe from 12,000 years ago. The archaeological excavations found the haplogroup R1a1 in Europe (Germany) 4,600 years ago (see above). In other words, for R1a1 in Europe exists a gap starting from the middle to the end of the third millennium BC (4,500-4,000 years ago) that lasted for 1,000 - 1,500 years. At the same time in Europe exists no gap in respect to the R1b1b2, their settling goes in a continuous stream from the 4,000-4,200 years ago, without any interruptions.
