It's entirely a thought experiment. There's no evidence for it whatsoever, and it doesn't even aim to be an accurate portrayal of even my shallow understanding

It's entirely a thought experiment. There's no evidence for it whatsoever, and it doesn't even aim to be an accurate portrayal of even my shallow understanding of the history of human precursors.
It's just an example of a scenario where only a thousand people have living descendants today that isn't "a volcano erupted and almost everyone died" or something.
