Like everyone else, humans co-evolved with other species, from microbes to intestinal worms to large predators, but many of those species are no longer with us in meaningful numbers. #RobDunn looks at the often negative effects of living around a species mix that is so different from those we evolved with: we might not miss being hunted by leopards, yet parts of our biology do. Fascinating #PopScience but a little prone to wandering off topic. #FinishedReading #bookstodon @bookstodon
