The theory of evolution is a change over a period of time. The theory explains how the species had an advantage and a disadvantage. the ones with the advantage survived and reproduced and the ones who had a disadvantage the specieces died out. the advantaged ones are called superiors and the disadvantage are called inferior. Basicly natural selection eliminated the inferior sepecies. So when nascar first started they used regular everyday cars and up to today they changed a lot. They are now well constructed stock cars and they're a lot safer then when nascar first started.
