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.

Beastly Britain by Karen R Jones review – how animals shaped British identity

A revelatory cultural history of our relationship with native wildlife, from newts doing handstands to Mrs Tiggy-Winkle

When newts go a-wooing, sometime in the spring, their signature move is the handstand. Girl newts cluster round to watch, while the boy newts flip on to their creepily human hands and shake their tails in the air. The waggiest newt is the winner, although the actual act of love is a strictly no-contact sport. The male deposits a packet of sperm on an underwater leaf for the female to collect and insert into her own reproductive tract. The whole business is best thought of, says Karen R Jones, as a “sexually charged game of pass-the-parcel”.

This kind of anthropomorphising often strikes naturalists as unscientific or even downright distasteful. But Jones is an environmental historian and her methodology allows, indeed impels, her to start from the principle that Britain’s human and animal populations are culturally entwined. Consequently, we cannot “see” a fox, hedgehog or newt without bringing to it a rich stew of presumptions and fantasy, drawn from childhood picturebooks, out-of-date encyclopedias and, in my case, the 1970s TV classic Tales of the Riverbank, in which small critters say funny things in the West Country burr of .
