> There are indicators, for example, the neanderthals and all other human like great apes have mysteriously disappeared except for us. (Or gotten assimilated, I mean, we have a tiny bit neanderthal DNA)
That's not an indication at all. It's an outcome.
> Also look at how violent humans are to their own species.
Humanity has grown to 8 billion organisms - the evidence seems otherwise.
And, large parts of the planet, haven't been invaded and the men killed, women raped, the last hundreds of years, in some places not even the last thousand years. Then, violent traits (reproducing by killing all men in the tribe nearby, raping the women) start fading away. (Not noticeable in a single lifetime though)
So its just guess after guess. Now it seems non subsaharan people have some neanderthal dna, they were more capable than we thought and some theories say they could see in the dark
Interesting, what are you basing that on? (Is it an observation you've made or is there any research paper for example)
But the neanderthals, that was about 40 000 years ago they started disappearing. That's so much time, so any more kind or more brutal traits they might have had, wouldn't matter any more. Evolution is pretty fast, 20-50 generations is fairly much, when it comes to changing the distribution of traits that already exist, from what I've read (both our own species and other). And seen, actually, about humans.
Personally I believe all other great apes were roughly equally violent, just not as intelligent.
Or maybe the technical advantage was driven by survival and desire to occupy/expand which eventually resulted in overall development (because you can only hide your advantage for so long) which lifted most of the boats resulting in conditions that make acceptance of others and cooperation easier. I would like to know large-scale examples of acceptance and co-operation when the world was being discovered, conquered, divided and shaped through occupation and wars.
Biden, Obama, GW Bush, Clinton, G Bush, Reagan, Carter, Nixon, Johnson, Kennedy, ... we've only chosen one 'psychopath', assuming I know what you refer to.
Nobody in the world has used them beyond that one pair of events.
It’s interesting how you narrowed it down to the “land of the free” when the gp speaks of a “species”.
