Homosexuality and Natural Selection.

The problem you are dealing with is the attempt to invoke teleology - the inference that everything is guided, or in some way goal-oriented. You can only point out that there is no evidence whatsoever that evolution is in any way a guided process.This is what the theists tend to dislike most about ToE - the fact that it posits no role for a god of any kind. Theistic evolutionists like to view the process as 'god's mechanism of creation' but it's just an attempt to rationalize their predetermined belief in a god.

I haven't had time to read all of this thread, but 'homosexual' type behavior is prevalent in many animal species and clearly has all kinds of fitness-positive effects. However, most of this is 'facultative' homosexual behavior that either serves to reduce aggression, or to (indirectly) increase chances of mating with females.I just want to point out that only 'exclusive' homosexuality would be selected against by natural selection and that is the exception rather than the rule. The only way to demonstrate NS advantages for exclusive homsexuality would be through models of inclusive fitness.

I am not aware of any reliable examples of exclusive homosexuality in animals. I would be interested to see any reliable scientific report to that effect, but I doubt any exist.EZ
