The nature of sexual attraction. What makes a human attractive/unattractive.

Since the earliest days of the Paleolithic Era, humans have had a specific attraction toward others of their own kind. Intentionally, those feelings are actually a part of nature that homo sapiens share with all other members of Kingdom Animalia who reproduce sexually. While many will argue that sexual attraction is controlled by a sex gland or society, the truth is that it is determined by a pea-sized gland, ironically located on the brain, called the hypothalamus.

The hypothalamus regulates homeostasis. It controls many emotions and feelings naturally needed for survival.

Hunger, thirst, self-defense, and sexual reproduction are included in that list of important sensations. Just like the brain tells an organism when it is hungry, it also signals the body to react when an attractive being walks by.
