There is no proof, no matter how ironclad, that YOU would accept, Goofball.

I'm content to go along with the most authoritative data that geneticist come up with. THEY say that they're sure the gene--or genes--are there, even if positive identification hasn't been made yet.

Some geneticists, however, maintain it has been found. But there is not yet universal acceptance of this, so I'm content to wait until they arrive at some conclusion.

That's the intelligent thing to do.

I'm not sweating it. So why are YOU all lathered up?
