*This is in no way supposed to be a hate post* Nordic people are said to be physically very fit and smart. It was said be Hitler that they were the superior Aryan arce. Then Ashkenazi Jews are very good at chess. People from certain regions in Africa are great runners. There are loads of more examples. Now is it true that some cultures are better then others in certain fields, is there any scientific evidence? And can other people too emulate that gene found in people with exceptional abilities in further generations in the future by changing their DNA? P.S: i am still a kid who is learning, so if this question does not make sense, forgive me.
