Regarding a recent letter on evolution: Your kids have a bad gene and no longer can see red. Big deal. One of your many predators happens to have a red tint to him, making it harder for you to see him. He eats better and is stronger. He has more kids. His kids are even redder. They have more kids. Soon all the predators are red and you can't see them.
That is evolution.
