This transmutes any random invertebrate facts you encounter in the future into deeper synthetic knowledge about how life works. (It also makes it easier to remember the original fact if you need tidbits for cocktail parties.)

And so, when you encounter new information about an invertebrate you can integrate it into your model for the relevant group.

(I say "at most" because some of the clades are nested within others, so an animal can technically belong to more than one.)
Reading the book lets you build a mental model for each of the groups.

The fun animal facts are numerous in a book like this, but my primary interest was the comprehensive framework it offers for thinking about animals. Every animal known to science belongs to at most one of these 50 or so groups

It was great to get exposed to at least some of the big debates and figures and is reasonably readable. That said, I think my next book in this area will be something a bit more systematic.

This book isn't a comprehensive survey of philosophy of photography nor does it put forward it's own synthesis on the topic. Instead it covers a small set of authors and philosophical debates in the field that the author found interesting.

(2) it's fairly recent in the grand scheme of things, so there isn't the same pressure to trace the literature to the dawn of time, and (3) photography is something I've found cool for a long time.

I picked a book on photography because (1) it has an applied aspect to it you don't find in a lot of fine arts (people create photos for practical applications like journalism and science in a way that isn't really true for painting, sculpture, etc.)
