Sometimes I wonder what our world would be like if our evolutionary relatives were still around. How would things be different with intelligent cousins like Neanderthals in the mix? Would we just be perpetually trying to kill them off, since that’s probably what helped them originally go extinct? Would there be nations of Neanderthals or would we intermix? Would their be stigma with interbreeding (which we know sometimes happened) or general species-ist stereotypes? Would there still be tension from the genocide we inflicted on them ages ago, with reparations to current Neanderthals or monuments to those who lost their lives?

Would less intelligent cousins who still had primitive language, likeĀ Homo heidelbergensis, be relegated to a lower class? How would we treat our even more distant cousins like Austrolopithecus? Would we grant them some special rights above other animals, like we sometimes do with intelligent animals like dolphins and chimpanzees? How would the ethics of genetic testing work when trying to get samples from our cousins who are not intelligent enough to consent, but are still more intelligent that what we currently research?

…This is what a human evolution researcher with a penchant for science fiction daydreams about. I guess I’ll add it to the list of “Books I should write but probably never will.”
