maybe for the purpose of evolving the human race for the everyday living,,so people can cope to whatever changes may happen to their environment!!! with their new ability they can live freely and easily... word there is evolution but for some occurences ( i don't know that ) certain Countries oppose to their ideas/ideals so they allied themselves and destroyed that Ancient Kingdom!!... i don't know what might happen,,it's all in Oda-sensei's hand,,,that's just my assumption' theory about the Devil fruit/Ancient Kingdom History!!
