I look forward to reading this, too! On this theme I just finished and thoroughly anjoyed another fascinating book, "Germs, Genes, & Civilization: How Epidemics Shaped Who We Are Today", by David P. Clark. I got it as a freebie
(in fact, a repeat freebie), so it may come back (it is no longer free at amazon UK nor DE, but there is no price on the US site).
Thank you Koland, Arcdata and Greencat for all this nice finds!
