Good luck trying to figure India ;). A world without sexual selection would be a somber place, lacking the rich medley of stimulating sights, sounds, and smells that help individuals win the evolutionary prize of reproductive success. Sexual selection was Darwin's second great idea 1 , and we recognize it as a potent and widespread evolutionary force that probably interacts across the whole genome 2. Dry sex We also recognize that sexual selection penetrates far beyond mating: With this greater depth and breadth of importance for sexual selection, modern evolutionary biologists have been facing questions similar to those that confronted Darwin and discovering an exciting diversity in reproductive form and function at the intimate level of the gamete 5. In PNAS 6 , a comparative study of closely related water beetles reveals this diversity through a remarkable complexity of adaptations in sperm form and function, and analyzes their coevolution with an equally remarkable elaboration in female reproductive tract architecture. Although the uniform function for a sperm cell is fundamentally to transport the male haplotype to the female pronucleus, the diversity of sperm form and function is far from uniform.

I believe we were made in God's image, God has no sex. And let's say he made man and woman, there's nothing saying that variance is an abomination.
