@fossilesque I was super confused by the title.. but the article makes a lot of sense.

A better title would be something like “New study reveals evolvability itself can evolve”.

Evolution better not evolve another level because I’ll be damned if I retake calculus just to understand salamanders. I’m not even sure if my TI-89 would power on anymore. (I’m old so if it does, tip o’ the hat to Texas Instruments.)

Annoyingly vague title... Why not just say "new study shows that evolution can occur at different rates"

Isn't this just evolutionary radiation?

Yes, the title is typically bad, unfortunately.

Then in the article itself, I was hoping for a mention of the difference between regular ol' Darwinian evolution, and the internal dynamics that fueled the Ediacaran and Cambrian explosions of sudden biodiversity.
