My understanding is that statistically, a lone man who travels to a faraway
location is *very* unlikely to have exactly one, or just a few, male
descendants two thousand years later. Most likely, his male line will die
out, as most male lines do (except during a rapid expansion). Rarely (or
during a rapid expansion), his line will succeed, and produce a multitude of
male descendants whose yDNA will show their relationship. Can a
statistician confirm or deny these probabilities?

Perhaps I should have stated the alternative hypothesis more clearly: That
the small amounts of K2, E3b, J1, and I1b-Western and I1b-Isles are remnants
of what were once much larger migrations. Through war, out-competition,
etc., the newer haplogroups R1b, I1a, and R1a have become predominant only
since the LGM.
