Not all of Spanish-speaking people nowadays came from Spain. Taking into account that Spanish people conquered American lands in the XVI - XVII centuries, you may guess that people from Venezuela, for example, have evolved in a different way than European Spanish people since the culture, habits, weather... are quite different.
