I bought this book because I thought it was about the "spectrum" of hunter-gatheres, the variety of what is out there. That is NOT what this book is about, but I still enjoyed it immensely.
This book is the study of human behavioral ecology. It begins with the same assumption that The Origins of Political Order did–human societies evolve to have certain characteristics the same way human bodies do. Societies are the way they are because those characteristics won the battle of natural selection over time.
This book attempts to answer a question I have been seeking an answer to for a long time: What is the actual ORIGIN of political order? Or as this book correctly calls it–hierarchy. Mobile hunter gatherers are almost always hard-core egalitarians. When and why did that change? Who was the first person to accept inequality, and why on Earth did he?
The author postulates that there are four things that had to be in place for a society to morph from people who are disgusted by status-seeking behavior to people who live in social hierarchies with hereditary leadership, political dominance and inequality.
1) sedentism: People chose to settle when there was an abundant renewable resource, like a river and they didn't need to move for food.
2) a controllable resource: People settled near a bend in a river with a great fishing spot that the tribe could guard
3) a resource that must be controlled: If the tribe followed their hunter-gatherer ethos of allowing anyone to come fish as much as they like, they themselves would starve, so they MUST control the resource.
This is how the first lower-class of people happened. Group A has maximized the amount of people that can live happily around this one fishing hole. Group B suffers some calamity and comes seeking food from group A. Group A has no motivation to share, so they offer to share with group B provided group B gives half of what they catch back to group A. Group B is paying taxes! And group A doesn't have to work as hard and suddenly inequality is born.
And finally, the most interesting factor:
4) child spacing: Mobile hunter gatherers space their children four to five years apart. Sedentary peoples tended to have children every one to two years. When this change happened, the group ethos changed because children got less attention from their parents, especially their fathers, and were raised largely by their siblings rather than a community. In mobile groups there was rarely more than one person of every age, so there was little competition between children. (When a two-year-old was going through his "mine" phase, he could be completely indulged because there were no other two-year-olds with whom to fight.) When a mom has four kids under the age of five, personalities shift and become more competitive and also less individualistic.
Weston A Price would add that due to this kind of child spacing, the mother wouldn't have enough nutrients to pass onto each child (except the first born) which would have contributed to a different genetic personality–nutritionally stressed out fetuses tend to be stressed out, competitive people.
Regardless of all the different possible reasons why, children spaced closely together exhibit a different kind of personality and therefore grow up to create a different kind of society than children born four to five years apart.
So how can we create a more equal world and a world in which people are less interested in status-seeking and competition and have higher self-esteem? We can space our children five years apart, not put them into schools where they spend all day with people of the same age therefore heightening competition as a personality attribute, and continue to create a society that can be highly mobile. The more easily people can move to different locations, the less any one location can suck (because then everyone would move or “vote with their feet.”)
Another thing I found interesting in this book is that the author is very clear that the study of hunter-gatherers is the study of people who exist TODAY. It is entirely possible that they developed their strong sense of egalitarianism in reaction to the hierarchy of modern social structures rather than the other way around.
Note that when an egalitarian society fights a hierarchical one... the hierarchical one wins. Egalitarianism is NOT a good strategy, as much as we all like it.
I liked how this book explained why men hunt and women gather. Women nurse for five years so they can only do things that they can do WITH their children. This is NOT hunting.
I enjoyed how hunter-gatheres consider a man and a woman with two children incapable of surviving on their own without help. I think this is still true today.
One thing I did not like about this book is all the math. I love math but the math in this book was based on too many assumptions, and it just wasn't necessary. The author makes a mathematical equation about every decision hunter-gatherers have to make (should we stay here at this camp or move?) The problem is that there is not really enough data in any one category to develop the decision making formulas in a way that would give me confidence they were actually fact. The author acknowledges this every step of the way, yet he continues to make assertions (everyone would want to move if they had to walk longer than 6km because these six tribes do) and then formulas for how a tribe would make decisions. This reminds me of the problems inherent in the way we currently study things: Everything must be measured, there must be a numerical value. A researcher can't just write about things that he saw, he has to quantify them. I think this method lacks humanity. I want STORIES with my data, so I can draw my own conclusions.
Another thing I did not like about this book is that the author talks about gender inequality and how women were forced to marry men they didn't want to in societies with marriages arranged by elders. I don't understand how this is a female inequality issue--the guy is being forced to marry a girl he didn't pick too.
