Well, the theory about the innate sickness of two chickens reproducing from their own bloodline.....its not really all that bad when you consider that when God sent out from Eden Adam and Eve, they were the only two ppl in the world, and thus, they could produce only offspring that would be directly related.....even stranger when you consider that Eve was already adams clone, basically, made from his rib......but their children had to reproduce in the shallow end of their own gene pool.....so in essence, we are all related much more closely than we think.....
