Heather and Bret bring an interesting perspective to their writing, as a married couple and research partners. It was fun hearing them switch reading from chapter to chapter. I'm not sure if we're supposed to infer that the reader of each chapter was more of the SME for that chapter, or if they were more directly involved in shaping those chapters, or if they just read every other chapter to keep it even.

The best parts of the book are them sharing stories about their research, teaching, and child rearing. From the sounds of it, they could write a thrilling travel log/ memoir.

As many other reviewers have noted, the conclusions they draw about how contemporary society should work are not well reasoned, or particularly supported by the analysis of cultural and evolutionary forces they base it on.
