Native skill is largely a myth.
According to Matthew Syed in Bounce (a very good read) there are numerous fields in which native or genetic skill is considered the norm (sports, chess, math) but no studies support that hypothesis.
Conversely a number of studies actively disprove that native skill exists. Ultimately, barring true genetic freaks (Michael Phelps wingspan for instance) anyone could achieve any level of any pursuit with enought focussed practice and a degree of luck.
