I have no problem with being civil. But if someone is an ass towards me, then I return it in kind. I was just expressing my views. I can continue to be civil, but please don't assume that means I agree with you because I truly don't.
To start, I do seem to know more about this field than you. I enjoy learning more about nature and have done some studies on it and watched quite a few documentaries on animal mating and survival. You claim that you don't know something about the subject because you are not a biologist or anthropologist, but also say that that doesn't make them right either. While there is disagreement in a lot of fields of science, most do agree about animal mating rituals and how their kinds of seduction do work. You are wanting to refute proven facts by saying that just because someone is an expert doesn't make them right? Well, just from their field of study, they would certainly be a better source than you and the source you quote has been shown to be outdated and wrong.
Brightly colored animals are more noticeable to the predators that hunt them. Unless they are intelligent and strong enough to survive, they will not live long enough to mate. That is why displaying their colors is attractive. They are proclaiming "I have all this, and I am of superior stock that allows me to survive with this." Also, most women react well to flashy men in general, be them animal or human.
