Abstract

Sexual selection is an evolution of Charles Darwin’s natural selection theory, and the outcome is male sacrifice regardless of cost. We first examine the mechanics of sex to perform with a partner in sexual activity. We then examine how Leonardo da Vinci’s curious studies of the sexual act and human sexual organ reproduction painting are complicated between the mind and body. We further discuss male love and non-human animal homosexuality, revealing the understanding of a gay man’s loved nest, which highlights that Darwin’s natural selection is not all-powerful and is fairly common in animal kingdoms. Finally, we support Darwin’s metaphysic, which comes from a transmutation accompanied by psychological and religious self-discipline in the mind.
