high IQ of Ashkenazi Jews + persecuted past - a link?

That's funny. That would mean sailors, people who lived on houseboats, beach side communities, etc. would all be susceptable to it too.

I can't see how persecution has anything to do with why Jews get Crohn's disease and it's derivatives.

Anyway, it's kind of hard to say there's no scientific proof that race exists now.
