Reddit mentions of The Hadza: Hunter-Gatherers of Tanzania (Volume 3) (Origins of Human Behavior and Culture)

The Hadza are a pretty good example of this. They are a hunter-gatherer group in Tanzania. There were multiple attempts by the government throughout the 1960s and 1970s to resettle them and instate a formal education system. These attempts failed, to say the least. They are mostly living the same way as before, hunting and gathering, though now they wear more clothing and use aluminum pots.

For more info about them (their society is beyond interesting), I'd highly recommend "The Hadza: Hunter-Gatherers of Tanzania" by Frank Marlowe, who is the undisputed expert scholar on this group.

I really liked The Hadza: Hunter-Gatherers of Tanzania by Frank Marlowe. It's about the modern day Hadza, who are, as you might have guessed by the title, hunter gatherers. The author tries to gain insight into what early humans might have been like by studying the Hadza, while still being very clear that the Hadza are not early humans. It mainly focuses on physical anthropology and spends a lot of time on details, like caloric intake per day, the specific species of berries they eat, and average skull size in the population. But you also get an in-depth look at the everyday lives of this modern hunter gatherer society. The author also analyzes their behavior through the lens of evolution, so you also get a good introduction to human evolution.
