Hmm. This is interesting, definitely shows foul play involved with the introduction of this 'New King'.
To go on what glasses guy was talking about, Homo Sapiens over taking Neanderthals, context is needed. Homo Sapiens won the game not by being out right better than Neanderthals in the short term, but by the long run. Neanderthals were stronger, faster, and most likely smarter (bigger brain case for evidence). In a world where there was true Mega Fauna around every corner, they had the best biology amongst humans to deal with it. And it showed in their group structures, which were generally a handful of close family members. Homo Sapiens, by comparison, formed much larger groups simply because they were weaker. Their greatest invention, the alatl, was the result of necessity forcing them to create a tool that would let them hunt big animals without having to get close to them. But even then, the Neanderthals got along just fine if not better...and then big animals start disappearing in an ever changing world. Being able to survive on smaller kills because you weren't so robust was efficient. Being able to form larger groups was very helpful when combating cousins. And honestly, fighting a few Jocks who're running on fumes as an army of well kept normie is not unfeasible.
However, that didn't stop Neanderthals for continuing to exist via their hybrid descendents. Which would be my only issue with this 'New King', why wipe out Homo Sapiens? They are energy efficient if but a little weaker and dumber, they have comparatively good social structures that allow for creating greater societies, and even if you interbreed with them a little the genes of these hybrids father typically stand out more as the children are just going to create more children with other Neanderthals.
I'm not going to be jaded into thinking 'muh racism', you can just see the low hanging fruit and that's a little stupid. But I get the feeling this is going to be one of those "Humans Bad, we need to be about Nature and the Environment y'all".
