the North European estimate, 31 on the Southeastern European, 5 on the

results are far less uncertain than the others."

Yes. You took the words right out of my mouth, John! The "statistical
uncertainty" is only 5% for "M." But, what do the confidence intervals
on Charles's triangle chart tell us about his "M" ancestry?
