Anatole I don't understand what you are doing here : it's a subject on lactose tolerance. Lawrence made a good point (I think) pointing in the paper under discussion a "hole" in the statistics and this is really puzzling and anyone could understand his point. Your comments on how exactly he describe the genetic proximity of poles and Russians are very much out of range in this discussion.
Do you have any input to bring to the lactase subject ?
