Stefan, I think you, also are confusing natural selection with selective breeding. Previously you'd not mentioned humans - who are very selective - and we were discussing snakes.

Has the topic changed or the equation been added to? Humans, yes are selective, or I think subjective, when partnering. I think we need to not split hairs and tangent. We were talking about snakes and their morphs; humans at that time were not involved.

Unless I've missed some new idea on the subject - which is possible - I still feel what I think to be true, is true.
