ELI5: How does natural selection explain homosexuality?
gpt
Natural selection doesn't require individual organisms to have descendants.

Worker bees and ants are all asexual except in rare instances. Although they don't pass on their genetic materials, their existence allows their relatives (queen) to continue to survive and pass on genetic information to future queens and drones to make new hives.

Likewise, homosexual individuals may not produce descendants at a similar rate to heterosexuals but as a highly social species, humans can support one another within an extended family. Grandparents can only do so much and parents may be too occupied with raising their own children. Homosexual individuals can help support their relatives to help pass down their related genetic material.
