so Eurasians evolve into hispanics and white guys when they age?

These characters are supposed to be the descendants of genghis khan or one is and the actors who play them change race with age, the baby is asian, the child is asian, around 10 or so he gets redish hair and starts turning white, his bff is also asian until finally when they are adults one turns into a hispanic guy and the other becomes a full on white guy with light hair. Still not as bad as John Wayne in the Conquerors but yeah.
