Some interesting genetic stuff in here on non-Jewish Euros also.
This contradicts other genetic studies I have read.
One study says that about 50% of Europeans are descended from a man in Northern Pakistan 45,000 years ago and made their way to Europe via Russia. The other 50% are from relatives of the same man who made their way to Europe via the Middle East a thousand years later.
So..........
The Ashkenazi Jews have the hightest IQ of all others in the world.....80% of the Jewish immigrants to the USA are the Ashkenazi variety.
