  1. Hang on, go back to the pink map near the end ... there's R1b's in northern Russia and central Africa. I'd love to know why? Not relative to this video but I recently learnt that small parts of mitochondrial dna can be passed down theough the male line and is reseponsible for some genetic abnormalities.
