AshkeNAZI roughly means "German", which implies a German / Jewish hybrid. Jews are taking the credit for this brand of brain architecture however the German "rocket scientists" of yore had something to do with it.
Germany has been a hotspot of envy and tribal warfare for a long time, the product being higher IQ. The German language has several words to describe subtle variations of envy. The Germans mounted "envy heads", monster faces over their doors, to scare away the envious with evil intent. The Jews are also a product of tribal warfare envy for thousands of years.
About half the Jews in Europe were killed during WWII. In general, with many exceptions, the ghetto dwellers died disproportionally while the Einsteins tended to get away. That's why Jews in America today have the reputation of being pretty smart and not welfare takers. Possibly WWII resulted in the largest amount of human evolution to occur the last 100 years, yet that evolutionary jump and its mechanism cannot be investigated by any academic that wishes to remain employed.
That was uncalled for.
'Ashkenazim are German Jews just as Sefaradim are Spanish Jews. 'Ashkenaz is Germany, Sefarad is Spain.
