I’ve heard that neanderthals interbred with the ancestors of modern homo sapiens.
But interbreeding suggests a binary male female heterosexual orientation. Which then makes one wonder how Neanderthal society dealt with the lesbian, gay, bisexual, and transgendered Neanderthals.
Probably the way nature always has. Like any other sick animal. Pushed to the outside of the herd as prey for other predators.
