In studying evolution, there has been much debate over the origins and evolutionary maintenance of sex. This represents a great challenge in evolution as it appears that the vast majority of animals and plants reproduce sexually. One component compounding the mystery is the two fold cost of sex, that is, there is a cost to producing males. Where an asexual species can double its population each generation, the sexual species will remain at a constant population if both populations produce 2 offspring per generation. An added cost of sexual reproduction can be that there is a time investment in finding mates, as well at the potential for sexual selection which can lead to the selection of unfavorable traits.
