Either way, though, it goes to show that the societies of Great Apes provide an ineffective illustration of any fundamental "human nature". When both candidates differ so significantly not only form humans but from each other, it becomes nothing more than a desperate appeal to nature.
Well, sure. We may be as different from chimps and bonobos as they are from each other - but the reverse is also true: We may be as equal to one or both of them as they are to each other.
Perhaps, but I don't see what bearing that has on the concept of human "race".

(Um, no pun intended.

)
Do keep in mind, Murky is suggesting that we consider Africans and Eskimos to be distinct species, or at least sub-species, which is, well, that's a special kind of creepy.
Well, I learned that a specie means that two individuals can have fertile offspring. Furthermore, I see species as being different beings, and races as being variations within one specie. Now, if you say that polar bears and kodaks have undergone speciation and are now two different species, that seems wrong if they can still have fertile offspring. But if you feel able to distinguish between two races of bears to such a degree as naming them different species, then couldn't it follow that Murky is in his right to consider Eskimos and, say, Bushmen, as two different races? Saying they are two different species is wrong in any case, as a pairing of an Eskimo and a Bushman can most definitely have fertile offspring.
Oh yeah. But if you're going to acknowledge that, what's the point of being a social darwinist?
I mean, from that perspective getting rich IS a bad trait. Getting rich requires long term planning and expectation of survival which is bad for having lots of kids. I know some extremely darwinian-fit young men who had more then the average number of kids before they were through high school. Now THERES a darwinian superman.
But all those guys can have offspring that grow up and survive precisely because our society does not allow Social Darwinism - that's the point of our welfare programs, right?
Which hunter-gatherer society is this?
Your problem here is that humans, even hunter-gatherers (maybe even the H-G gang more than most) are damn inventive people. They get up to all kinds of tricks not covered here.
And social status effects under such conditions... Well, it might not be quite what you think. A very famous example from the Khoi-San (in non-PC "bushmen") is how the best hunter does NOT get the choiciest cuts of meat if he brings down a prey. It's divided up according to strict rules which actually maximises his usefulness as superb hunter to the GROUP. (Iirc he gets the head, not the choice cuts of meat.) But since the group is a pretty tightly knit family entity, genetically speaking it might still work out fine. Just not in such a way that this presumed über-hunter-gatherer necessarily profits the most. (And as you said, they have some wacky ideas about private property as well.)
The thing is, human envy is a powerful emotion and needs to be checked. Well, if you're this über-hunter, general smarty-pants, super-strong and tough guy in this kind of society, and then start demanding everyone subject themselves to you as and effect, chances are it's going to get someone's goat eventually, and you will end up with a spear through your ribs in a "hunting accident". It's the same reason if you have something extra nice, and someone admires it, you give it to him. Eventually someone else will make the same observation, and the thing gets passed on, so eventually everyone takes turns owning the nice stuff. This is what tends to happen in that kind of acephalic, non-stratified society. If you're this über-hunter in an already stratified society things will tend to work out more like you have described them.
The second problem here is that in the H-G societies we know of, the actual survival tends to depend not on the occasional game the men bring home, but the continuous daily scrounging the females are engaged in. The group usually could survive on that alone, making these hunters a bit of decoration at times...
And on top of that we get sexual selection. I.e. the wimmien tend to chose whether and what kind of rumpy-pumpy there's going to be...
In whatever society humans exist, conflicts of interests
will occur. When that happens, the most powerful
will have the final word. It may very well be that the Khoisan are putting the groups interests first, but that can only be possible precisely because the group is small and all members are related in some way. However, because of the dangers of inbreeding, I am sure that there is contact with other, nearby groups. And there is no reason to expect that the groups then act "egalitarian". In fact, murder and violence rates are extremely high among hunter-gatherers, compared to... civilized societies(??).
And it would never be like "one guy tries to dominate the entire group". It would be much more effective if three or four guys go together and decide to dominate the group in unison. Though there may still be one most dominating among them, because the others also profit on it, they will keep it going. An alliance like this will allow a few dominating men to control the group.
And finally, who do women prefer to mate with? The high status, powerful, intelligent, fit and able men. In fact, something like 80% of all women who have existed have descendants who are alive today, but only 40% of all men who have existed have descendants. This is only possible if a few men got many women, and many men got none (either because they were killed, died of disease or starvation, or were never found worthy of a woman). Human sexual selection has never - and will never - be egalitarian.
Dawkins explained it very well, evolution are how humans should morally treat each other have little in common. We have rational & compassionate minds which allow us now to take the reigns of evolution ourselves to some degree. We don't have to dominate & destroy "weaker" people anymore just because we can.
But that still doesn't say anything about whether we shouldn't...
Most hunter-gatherer societies are monogamous, so... I disagree? And also wonder why you believe that social status is necessarily something accorded to men alone, given that there are many human societies exhibiting, to some degree, tendencies towards gynofocality?
Of course social status is not accorded to men only. Social status is something every being in a group has, whether it is a male, female or cub. However, social status is more important for men because it is a sexual selection trait that women look for. Men doesn't care much about a potential mate's social status (as long as it isn't too low for the wrong reasons...). If a woman is young and beautiful she has already achieved close to top score. Men on the other hand has more to win and more to lose by whether or not they have a high social status. Thus, men compete more to gain higher status, men risk more for it, and men are driven more towards it than women.
And while hunter-gatherer pairs may be mostly monogamous, it is fully possible to have serial monogamy. Remember that traditionally, a high percentage of women die in labour, which means that the man is then available to get a new woman.
