I guess that's why the experts keep paying huge dollars in stud fees for the right to a vial of jism from the top champions huh? You conveniently forgot the other part of that equation. While most of the offspring of champions don't become champions, most of the champions are the offspring of champions.
Desire is great but it simply can't overcome LOFT (lack of f'ing talent). You can go out every day from the time you walk and run sprints but if you weren't genetically blessed with enough fast twitch muscles, you'll never compete in the Olympics in the 100M dash. You can shoot hoops, dribble, run sprints, etc. all day long for your entire life but if your 5'5" Parents provide you with a 5'5" body, you're not playing in the NBA.
You talk about this desire thing all the time, so what is it you desire so much John? What are you world class at? Seems like, since you're convinced that desire is pretty much all it takes, either you're world class at something or you're cursed with apathy. So which is it?
BECAUSE racehorse are CHOSEN from stock bred from champions. So obviously any horses that become champions will have had a champion pedigree. People aren't going to persia to capture wild stallions to enter into the Kentucky Derby. The horses are weeded through to find the ones that are willing to run and those horses are intensively trained to run. Unlike the movies they don't go from plowhorse to triple crown winner.
Yes, in ANIMALS other than humans, if you selectively breed for traits then you get those physical traits. You don't get the psychological ones necessarily. However it's certainly possible to attempt to breed for psychological ones. This experiment was done in Russia with foxes to try and determine how long it would take to breed domesticated foxes. The experiment was simple, fox pups that bared their teeth at humans were killed and fox pups that were friendly and curious were bred. In short order the foxes were coming out like dogs, friendly with droopy ears.
And of course folks go the other way and breed pitbulls that are exceptionally game and roosters for fighting etc....
And this all may be possible in humans as well. When you're ready to set up you're own human breeding farms to breed for traits let us know......Shane is probably available for a stud fee. But for now it's just guessing to assume that one person is born with a "sports gene" while another is not, especially if the subject is some random person who just happens to be successful.
As the other old saying goes success is 99% perspiration and 1% inspiration. And so far that's proving more true than any other theory according to the studies.
Even the brilliant Nikola Tesla who said his ideas just came to him had a thorough grounding in engineering and a lab to test and refine his designs. He took the 1% inspiration and put 99% perspiration behind it.
