Everything Evolves by Mark Vellend review – can Darwin explain JD Vance?

Why evolutionary theory should be applied to peacocks, politics, iPhones and quite a lot in between

Nobody expected the Spanish Inquisition, but then again no one could have predicted the giraffe, the iPhone or JD Vance. The laws of physics don’t demand them; they all just evolved, expressions of how (for better or worse) things happened to turn out.

Ecologist Mark Vellend’s thesis is that to understand the world, “physics and evolution are the only two things you need”. Evolution, here, refers in the most general sense to outcomes that depend on what has gone before. Thus the world can be divided into things that are inescapable and things that are contingent, depending on circumstances. In the terminology he borrows from evolutionary biologist Graham Bell, the study of physical necessity is the “first science”; that of historical contingency the second. So, the periodic table of 90 or so natural elements, which are inescapable given the laws of physics, would fall under the first science. Dung beetles and vice presidents, which aren’t, fall under the second.
