So I clicked over to Pharyngula to see whether PZ had blown his top about the Fish thing (see previous post). Yes! In a manner of speaking.
I feel the need to cheer poor PZ up. So: the coolest thing on Flickr is this set of scans from a 1972 biology textbook that so desperately wanted to be a prog rock concept album. You should also read the tart commentary by the guy who posted it.
I thought about posting a few of the images here but I think, for full effect, you just need to view the whole set. (Just like you can’t really explain to someone why a particular Yes album is great by playing only 10 seconds of it.)
