PS Why would an intelligent designer give us (humans, gorillas, and [bleep]), the gene for manufacturing vitamin C, then turn that gene off so it didn't funtion? If he didn't want us to have that ability, why not just leave that gene out altoget
Pretty good example of how evolution doesn’t go the way you think it does.
Sometimes mutations are neutral when they occur, so don't get weeded out of the population. That's what happened here. In an environment rich in foods containing vitamin C, the loss of a functioning C-making gene had no effect good or bad. It was only when we lost that year round access to dietary C that it became a disadvantage.
