Don’t you ever get tired of pulling stuff out of your…of making things up as you go? We just had a thread discussing a paper on the Y-chromosome bottleneck in humans. The scenario which best fits the data is human societies underwent lots of male dominated clan warfare between 7,000 and 5000 years ago which led to lots of male deaths and the male (y-chromosome) having greatly decreased diversity in the human population.

Sorry but the science once again directly refutes your speculation.
