Most humans, including you, belong to the 99.9999% of Homo sapiens that are isolated from the much smaller isolated groups left.

On the other hand: can you imagine how regressively conservative—including in ways with which you cannot already be familiar—a society that small and that long isolated is? We know ≈nothing about them, but what we do know includes that women there once distracted the men from further attacking outsiders by way of sensual touch.
