This study was simply a confirmation of earlier hypotheses. This is what we talk about when we mention that scientists are always double-checking each other's claims.
Unless you graduated from high school in the last couple of years, odds are genetic testing wasn't available to the folks making that claim.
Sounds like a slam from a swabbie!
While in the Coast Guard, the irony of the swabbies giving me shit for being a puddle pirate while we towed their broken-down POS rigs to port was lost on them.
Thanks for serving.
