Aenigma, enigmas, and the progress of science

I’ve celebrated many a Latin name on Scientist Sees Squirrel, sometimes for something as simple as the way it sounds, but more often for a story it tells.  But this time, I’m celebrating the loss of a Latin name.  Not because I didn’t like the lost name; I did.  But its loss – or, more precisely, its replacement by a new name – has a lot to tell us about the process of naming and the progress of science.

Latin names that amuse my inner 9-year-old: Onopordum acanthium

I have a paper cut-out Nativity scene that comes out every year around Christmas (it’s a childhood tradition that’s stuck with me despite my lack of religious conviction to give it meaning).  There’s a donkey near the manger, of course, and seeing it reminded me I’ve been meaning to mention the wonderful (?) etyomology of the Scotch thistle’s Latin name.  Scotch thistle is native to Europe and western Asia, although it’s become invasive in many dryish places around the world.  And it has a Latin name with a certain je-ne-sais-quoi.

Quite a while back, I wrote about the black-billed thrush, saddled with the quite unfortunate name Turdus ignobilis.  It doesn’t quite mean “the ignoble turd”, but my inner 9-year-old would like it if it did.  But Scotch thistle – ah, my inner 9-year-old can go to town.

Three witches in the woods

Happy Hallowe’en!

Tonight, you’ll no doubt see neighbourhood children traipsing door-to-door in costume, shrieking and laughing along the way.  You’ll see superheroes and scarecrows, pirates and police officers, wizards and witches. Some costumes go in and out of fashion; but there are witches every year.

There are witches in the woods, too.
