Nature, Nurture and Proximity

I believe that there needs to be a third condition added to the title.  i.e. Proximity.


 It appears to me that virtuoso's have a propensity for a particular skill or aptitude which may be a genetic proclevity nurtured by its proximity to a supportive circumstance.  Pavarotti can sing but was his success facilitated by his environment? Michael Jordan can jump so was his "natural" ability augmented by the place and time of his birth?  My physical development is influenced by testosterone levels during gestation so does that trigger a genetic response and/or will my behavior be augmented by action, incident, or accident?
