Joshua Naterman said:I mean, anyone and everyone can substantially improve what they currently have if they are not super highly trained but when you're talking about the difference between 11.0 and 9.7 in the 100... genes.
If that's true, than how come the sub-10-second gene didn't exist before, say, 1968?

The gold-medal time in the first modern Olympics in 1896 (12.0 seconds!) wouldn't be enough to win a HS state meet at most High Schools in the country today. Franz Liszt purposely wrote his "Transcendental Etudes" to be so difficult that only he could play them. Today, any college piano major worth his salt is playing them. Are you going to call that genes? Are we evolving? Do sprinters and concert pianists of today all work harder than those a century ago? Of course not. This is why, in my previous post, I was careful to say practice how I practice, not just what or for how long. There are many corporate lawyers, business execs, and retirees who've played 10,000+ hours of golf. How come they're not all on the PGA? I think part of the answer is training - they don't look at every time they do something as an opportunity to improve at it. At why should they? While it's fun to be competitive, sometimes people just want to relax. Having your brain turned onto that mode all the time is exhausting. I think part of the answer is also that competitive spirit alluded to above. I also think part of the answer lies in technology, advancement of training methods, and our collective experience as a society. I have a theory that if you took Franz Liszt or Archie Hahn, put them in a time capsule as young children and zoomed them up to 2012, they'd still grow up to be among the best in the world.
