Leaping

I have mentioned that the ethnic group other than African-Americans that excels at basketball is Slavs.  I like watching Track and Field on YouTube, and noticed tonight that those are the two ethnic groups that excel at the high jump as well. Not shocking, when you think of it. West African descent (America, Caribbean, Canada) and a collection of Russians, Poles, and Ukrainians.  A German and couple of Swedes are also in there - but in basketball, not so much of those.  There are a few of everything else. Still, I think this Slav height+leaping is a genetic advantage similar to West African fast-twitch fibers.
