Nerull,

I wasn't denying that there are species with different color perception than humans. What I was saying is that the continued success of specifically hominid trichromatic color vision millions of years after it emerged can't be explained away by an anthropic argument. We didn't start out with a vast number of different hominid species with different inductive biases which were gradually pruned away until we (and chimps, gorillas and orangutans) were the only ones left. What happened was that hominid color biases were fixed millions of years ago, and then they continued to be successful. What I am asking is how evolution knew which biases to pick (out of the infinite number of choices) all those years ago.

Also, the question about the designer. I want to assure you that I'm not coming into this with any intent to vindicate ID. While I probably have less of a distaste for ID-type hypotheses than a lot of the posters here, I still see it as a position of last resort. Even if it turns out that this particular case of apparent design cannot be explained evolutionarily, I would look for other non-teleological explanations before turning to some kind of design hypothesis.

And how did you know to draw the queen of spades from that deck?

And who says our color vision is fixed?
