This author wants to point out SEVERAL times that he is trying to be non biased, but it is just overkill. The rest of the book is very interesting though.
I am sure this book is good for the academic. Sometimes it is even funny. But the narration style is monotonous, giving few clues to what the content means from a human perspective. This is not audio material.
It was so bad, that the end of the book came completely as a surprise, and left me wondering WHAT WAS the POINT?
Worse, it left me with WHO CARES?
Not I, not after listening for all those hours.
"Instead, it might very well be that once the civilizational process is begun, there emerges a feedback effect, which by making the more intelligent in each generation more fit for reproduction, gradually increases the overall cognitive ability of the peoples inhabiting the evolving civilisations. Being smart in civilization is beneficial for your chances of reproducing yourself, and so the smarties get more numerous. Mr. Diamond doesn't see this."
Our intelligence evolved in pre-civilized societies. In civilizations, it does not require intelligence to reproduce. In today's world, those who are uneducated and living in poverty are the ones reproducing.
No boubt that Prof JAred Diamond has done a great study, its highly recommended because he has put 30 years of experience in writing this book. Some time during this books he talks a lot about petricular topic like he gave so much detail about domestic animals, some times this book lacks interest but after a good patience finally it becomes worthwhile to read.
Jared Diamond is an excellent author, and so would this book be, if only his theorizing were true and unflawed. But it's not. He starts the book by stating that he's out to destroy the claim that genetic differences is the cause of the global disparity in civilizational achivement between different peoples and races, a claim he considers low and immoral. Then he proceeds by asserting that the inhabitants of Papua New Guinea are genetically superior to whites. This self-contradiction is not rendered any less stupid by the fact that it's done without reference to any evidence beyond the mere hunch of the author.
The main argument of the book is that different peoples have made civilizations that differ not because the peoples themselves are of varying genetic giftedness, but because they've been unequally procured by their respective environments with the ingredients necessary for civilization-building, chiefly: crops suitable for agriculture, animals suitable for domestication, soil suitable for farming, and habitats spacious enough to support the numbers of humans needed to preserve knowledge through hard times, and located in connection to other sites of civilization in an horizontal fashion, rather than a vertical one. This argument is all very well and quite plausible, but mr. Diamond forgets something. Although it's possible that it was the uniquely beneficial environment which laid the foundation for the Eurasian civilizational preeminence, that doesn't prove that all races are equally intellectually gifted today. Instead, it might very well be that once the civilizational process is begun, there emerges a feedback effect, which by making the more intelligent in each generation more fit for reproduction, gradually increases the overall cognitive ability of the peoples inhabiting the evolving civilisations. Being smart in civilization is beneficial for your chances of reproducing yourself, and so the smarties get more numerous. Mr. Diamond doesn't see this.
This book overlooks the entire anthropological history of humankind and comes to a screeching halt with the conclusion, "Location, location, location." This book pretends to answer "the big questions" about our origins, but is more about how geography impacted evolution. Important topic, but limited in scope.
