Summary:
- The article discusses the biological basis for the binary nature of biological sex in humans, with males and females being the two distinct sexes.
- It presents eight reasons why human sex is binary, including the presence of distinct sex chromosomes, the production of different gametes, and the development of distinct primary and secondary sexual characteristics.
- The article argues that while there may be rare genetic or developmental variations, the vast majority of humans fall into the male or female categories, and that this binary nature of sex is a fundamental aspect of human biology.
