Новый снип под L1029.
На данный момент преобладает в Восточной Европе.

Since the entire clade R1a-M458 (together with some other clades/haplogroups, including for example I2a-Din and some subclades of R1a-Z280, like R1a-Y33, R1a-Y2613 and R1a-YP340) is commonly suspected of being associated with the ethnogenesis of the Early Slavs, it is quite safe to assume that both L1029 and all its known major subclades (including YP263, YP416, YP417, YP446 and YP592) have arisen among the members of the Early Proto-Slavic community. In my opinion, both L1029 and YP417 are old enough to predate Kolochin, Penkovka and Korchak, three "parallel" archealogical cultures that are commonly considered to have been undoubtedly associated with the Early Slavs. Since at least two of those three Early Slavic cultures (i.e. Kolochin and Penkovka) show evident association with the earlier Kiev culture that arose on the basis of some Post-Zarubintsy groupings, one may suspect that YP417 was born among the members of one of those early cultures in the Dnieper-Pripyat region, and depending on how old YP417 is, this could be either Kiev, Zarubintsy, or even some earlier cultures that contributed to the emergence of the Zarubintsy culture. Unfortunately, nothing is known about the Y-DNA haplogropus associated with either Zarubintsy or some Pre-Zarubintsy cultures influencing the prehistory of this very region (including for example the Milograd-Pidhirtsi, Pomeranian and Chernoles cultures, among others), so it is almost impossible to assign CTS11962/L1029 to one of those early archeological cultures.
Depending on which method is used for calculating the age of YP417, one may come to slightly different conclusions regarding the potential association of this clade with some Early Slavic tribes. For example, some estimates suggest that this clade is relatively young (for example about 1700-1900 years old, as suggested by some recent calculations made by Šukasz Šapiński), although some other calculations (including my recent estimates) suggest some older dates for YP417, for example about 2000-2300 ybp, and I would also say that it seems premature to definitely exclude even much older dates (like 2300-2700 ybp).
Based on the current distribution of clade YP417 and its clear association with the Eastern Slavs, I would suggest a hypothetical scenario in which the YP417 clade was born among the members of the Zarubintsy culture (300 BC - 100 AD) who were likely to constitute a relatively heterogenous group of people (composed mostly of members of R1a-M458, I2a-Din and some specific subclades of R1a-Z280). Later on, this relatively small group of early YP417 members could have significantly countributed to the formation of the Kiev culture, and mostly to its North-Eastern part that was later transformed into the Kolochin culture, although some early separated sublineages of YP417 could have been included into the neighboring Penkovka culture or even into the more westerly located Korchak culture. This would be consistent with some preliminary results suggesting that YP417 shows the highest freequency among the Eastern Slavs, while some low frequency of YP417 is also expected to be seen in the Balkan peninsula (thus likely resulting from the southward expansion of the Penkovka-Ipotesti culture), or even among the Western Slavs. This would also mean that clade YP417 could not have been specifically associated with just one East Slavic tribe, like Krivitchi, Vyatichi, Radimitchi, etc., although each such tribe could have shown different frequency of YP417 (not to mention that some East Slavic tribes could have been associated with the presence of some specific subclades of YP417).
Please note that all above are just my theoretical speculations, and some alternative scenarios are perfectly possible. It is also worth noting that other members of our admin team may prefer some completely different scenarios when regards the ethnogenesis of the Early Slavs, including a potential contribution of L1029 (and YP417) to this process. I am also quite sure that some of my colleagues are very skeptical about using some data derived from the modern populations to conclude about the situation in a very distant past, and I must agree that only some future discvoveries based on the aDNA data will allow us to verify all these hypothetical scenarios.
