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 this piece [], and the author here accurately represents everything as far as I know. T...(read more)

There's a lot of uncertainty in this field. I would hope to see a lot of people very quickly shift a lot of effort into researching:
