Evolutionary biology is unable to reveal why animals would abandon asexual reproduction in favor of more costly and inefficient sexual reproduction. Exactly how did we arrive at two separate genders-each with its own physiology? If, as evolutionists have argued, there is a materialistic answer for everything, then the question should be answered: Why sex?
The evolution of sex (and its accompanying reproductive capability) is not a favorite topic of discussion in most evolutionary circles, because no matter how many theories evolutionists conjure up (and there are several), they still must surmount the enormous hurdle of explaining the origin of the first fully functional female and the first fully functional male necessary to begin the process.
Does evolutionary biology have any copasetic explanations yet for the origins of fully functional males and females, that this riveting little essay may have ignored? When a theist accuses us of not having an answer for this, in an attempt to fill in the gap with their favorite god, IS there an actual answer that we can offer them, other than “we don’t know, but we DO know it wasn’t your god”?
Not that it answers your question, but for reference.
