Reddit mentions of The Lifeways of Hunter-Gatherers: The Foraging Spectrum

In general, the concept of communal property is pervasive among egalitarian societies. Most mobile foragers or hunter-gatherers are or were egalitarian, as are many horticultural societies. However, there's a lot of variation. Typically there are complex social leveling mechanisms in place that prevent any individual from collecting too much wealth (including material and social). For example, when a hunter gets a kill, depending on the tool and method used and present company, there may be different culturally proscribed methods for distribution. Egalitarianism, putatively characterized the majority of human evolution but is hardly representative of all human culture. Robert Kelly's new edition of The Foraging Spectrum provides a nice review. Also, Boehm's Hierarchy in the Forest is a good introduction to theories on egalitarianism.

I would suggest The Lifeways of Hunter-Gatherers: The Foraging Spectrum. It is very comprehensive, informative, and readable.

You have to see the consequences.

If the division of labour is universally across all world societies sex-determined (e.g., men predominantly hunt, men predominantly fish, while females predominantly wave), then you have either very deep cultural roots for this that is shared by all human societies, but then it doesn't explain why the division of labour is such even when societies were significantly transformed and also why something like this wasn't changed by some disruptor. Another explanation might be that it is something formed by pressure in certain environments/conditions and the traditional society is inhabited predominantly such environment/conditions. But again, this doesn't explain the range of different conditions and you would have to explain this universal thing. Lastly, you can say that there is some sexual determinant, as suggested in paper and in other literature, this can be pregnancy and associated risk aversion, hormone levels and thus different behaviour and so on. Lastly, you can compare it with other organisms where you can clearly see different sex strategies and sexually determined type of behaviour, which often stems from the simple fact that female is the macrogametic sex and male microgametic sex and from this, you have different reproduction and parenting strategies.

Also, unless you have some new information that disprove old, the age of research is inconsequential. And this field didn't dramatically changed. No new information was added to ethnographic atlas so if you did the analysis now, you would get the same result.
