this news item about the influx of Steppe culture into the mix of 5,000 - 8,000 years ago. My haplotype is L2. In the older notation: R1b1a2a1a1b3c1. On YSearch one can check who else has this same haplotype. Many families from Devonshire and Southern England shared this haplotype, but also many from present day Kazakhstan! I'm thinking that I'm seeing the actual consequences of what this news article reports.
What this means is that my family-member Kazakhstanis and I have a remote common ancestor. It would be fun to find out more out him.
Note: June 28, 2015 - It could be that our ancestors met in Belgium. See posting on this date.
