This was a fantastic read! (In the interests of letting other people have more trust, I did some research on the Cambrian Explosion a bit ago for a project, and the author here accurately represents everything as far as I know. This is a really eloquent explanation of both what we think happened at the time, and why pulling data out of the fossil record is so damn hard and creates so much uncertainty. I don’t know much about Hox genes, but it seems totally plausible.)
