This is devolving into a silly 'no, you need to prove your claim, not me!' back and forth. FWIW, I'm definitely not a scholar in this field, but I'd like a plausible hypothesis for the extinction of entire Y haplotype lineages without the elimination of maternal lineages through just 'cultural diffusion'.
