exogenous Roman era York 3DRIF-26 is J2b1-M205 and likely Middle Easterner

The years 2014 and 2015 did provide useful ancient genomes NGS data in an increasing manner (see ancient J2-M172 genomes). For J2 the year 2016 could not begin more exciting: Martiniano et al published a paper about nine ancient genomes from northern Britain: Genomic signals of migration and continuity in Britain before the Anglo-Saxons. As introduction to the sample of interest […]

J2b-M205>PH4306: a little substructure for this isolated lineage

The diversification of J2b into M205,CTS560,PF7316 and the brother Z575,CTS2622/Z1827 seems to have happened a long time ago (YTree v3.12 16200 ybp) while the diversification of M205 was possibly only 5600 ybp. So this seems a long time of isolation without expansions if no so far undetected splits do exist. Using data from Hallast et al 2014 and Estonian Biocentre / […]
