The name of the song is called ‘Haddocks’ Eyes.’” “Oh, that’s the name of the song, is it?” Alice said, trying to feel interested. “No, you don’t understand,” the Knight said, looking a little vexed. “That’s what the name is called. The name really is ‘The… Continue Reading
Epistemology Bayes, evolutionary clocks, and biogeography 30 Mar 20122 Apr 2012 I just received a review by Gareth Nelson of Michael Heads’ book Molecular Panbiogeography of the Tropics (publishers’ site). I should have blogged this before, since I got a copy, being on the editorial board for this series (the same one I published with at Uni Calif Press), but I have… Continue Reading
Epistemology Are humans, apes, monkeys, primates, or hominoids? 19 Mar 201221 Jun 2018 I suspect the correct literary answer is that we are Yahoos, but here I want to do what I would ordinarily never dare do: disagree with John Hawks. John takes Jerry Coyne to task for calling humans “apes”: Humans are hominoids. Hominoidea is a taxonomic group. Phylogenetic systematics holds that taxonomic… Continue Reading
Biology Did Popper and Quine invent “Aristotelian essentialism”? 7 Feb 201221 Jun 2018 There are many narratives told about evolution. One of the most widely told is the Essentialism Story, replayed in textbook, popular storytelling and philosophy alike. It goes like this: Before Darwin, biologists were constrained by essentialist thinking, in which they were committed to species being natural kinds where there were… Continue Reading

Biology The taxonomy of disease 7 Sep 20117 Sep 2011 A letter in Nature Reviews Drug Discovery has argued that it is time to reform the taxonomy of disease. The authors are Ismail Kola, head of a pharmaceutics company, and Sir John Bell, Regius Professor at Oxford. The taxonomy of disease (technically called nosology) is an old one.

Ecology and Biodiversity Counting species 26 Aug 201122 Jun 2018 Suppose a scholar of toys wanted to count the number of kinds of toys in the world. Since this information is not generally recorded, the scholar might look at the ways toys are used, the sales figures, or the designs recorded in the patents and trademarks offices in order to… Continue Reading
Biology Domains, disciplines and levels 10 Aug 201110 Aug 2011 I have to get this out of my head so I can go do some real work (like finding some real work). Next time someone wants me to do metaphysics, they better come armed with a cheque. So if, as I have argued, reduction is one-layered in ontological terms, however… Continue Reading
