I was so engaged by the first half of this book. The research on domestication of foxes and dogs was fascinating, offering insight into human domestication through practices of cooperation. Clearly, the authors have substantive expertise here. Alas, the second half of the books veers into political opinion of a very uninformed sort. The authors become jingoist promoters of democracy, extolling virtues with limited evidence, neglecting other forms of government such as democratic socialism that rely more heavily on cooperation than does capitalistic democracy. Stay with the science, kids. Let us draw conclusions about political implications on our own.
