I'm developing a historical fiction idea that I hope will one day become a coming-of-age story, as it were. It's set in pre-history circa 70,000 years ago when Neanderthals and humans both coexisted together. I just wanted to know a few things as I get set on the preliminary research: #1- Are there any official records for names between the two species, or should I just make up some of my own that sounds reasonable? #2- How would a Neanderthal character have addressed himself? Same as the human? I assume they wouldn't have considered themselves Neanderthal or human respectively. Would it be unrealistic if I had them address each other by the modern naming? #3- My MC in this story would be around 14. In prehistory, people would've considered him/her old at this age, correct? Or at least adult? What would have been expected from him/her by this age? That's all I have for now. I'll continue doing research and developing this idea some more on the side. Prehistory is such an amazing, fantastic area of study.
