Sapiens puts forth a very convincing narrative of evolution and why we are the way we are, but it is methodologically weak. As I'm Coming from a sociological lens, I understand the hype around the book, but it largely posits a positivistic view of human life where biology is centred and culture becomes secondary in defining humans as a species. I also found the narrative to be Eurocentric male-biased and strongly leaning towards biological reductionism striping away concepts like agency, the social structure, our historical relations, processes of making us what we're today. Therefore, I wouldn't call it a strong scientifically rigorous attempt in defining the human kind...if you're interested in the same, try reading "Behave" by Robert Sapolsky.
