With a 95% probability, the most recent common ancestor of all members of haplogroup R-Z284 was born between the years 2817 and 1648 BCE. The most likely estimate is 2192 BCE , rounded to 2200 BCE .

R1a is virtually composed only of the Z284 subclade in Scandinavia. In Slovenia, the main subclade is Z282 (Z280 and M458), although the Z284 subclade was found in one sample of a Slovenian.

An analysis of the Hume DNA Project has provided conclusive evidence that the Scottish philosopher, historian and economist David Hume (1711-1776) belonged to haplogroup R1a-Z284 > S4458 > S5301 > S5153 > L448 > CTS4179. This subclade is …

Aug 12, 2021 · Surely enough the MacLeod Y-DNA Project has over 20 members belonging to R1a-Z284>L448, and some are confirmed for the YP280 subclade. Other lines may not have known descendants to this day but remain historically important. Knowing Ragnar Lothbrok's Y-DNA would also include the following royal lines.

The main clades within a haplogroup often match large ethnico-linguistic groups, which are usually displayed with a defining SNP (e.g. E-V13, G2a-L497, J1-P58, R1a-M458, R1b-U106). These main clades were for the most part formed during the Neolithic or Bronze Age.

Mar 26, 2014 · The R1a-Z284 subgroup is confined to Northwest Europe and peaks at ∼ 20% in Norway, where the majority of R1a chromosomes (24/26) belong to this clade. We found R1a-Z284 to be extremely rare...

Dec 30, 2022 · R1a-Z284 (TMRCA 4200 YBP): Haplogroup R1a is present at a frequency of 26.3% among Norwegians (Dupuy et al. 2006), 24.4% among Swedes (Lappalainen et al. 2008), and 16.5% among Danes (Sanchez et al. 2004). Most of the R1a in Scandinavia is of the Z284 branch, descended from the Battle Axe culture.

Y-SNP Branch Information on R1a-Z284. The Y-SNP branch R1a-Z284 is defined by S221, Z284. Additionaly, all downstream markers L448, S200, S223, S345, Z287, Z288 are defining this branch as well. For further information on a marker, please see marker details at Phylotree Y or consult the Y-SNP tree there.
