Evolutionary Theories on Gender
and Sexual Reproduction

Abstract
The origin and maintenance of sex and recombination is not easily explained by natural selection. 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? Is sex the product of a historical accident or the product of an intelligent Creator? The current article reviews some of the current theories for why sexual reproduction exists today. Yet, as these theories valiantly attempt to explain why sex exists now, they do not explain the origin of sex. We suggest that there is no naturalistic explanation that can account for the origin and maintenance of sex.
