I meant to post this Saturday and just blipped on it.
I realize there have been no new installments on "Earth: A Biography" for a couple of weeks. Partly it's because a lot was going on before we hit the Cambrian -- new kinds of land formation (think "limestone") and a couple of significant mutations in living organisms. We just don't know for sure how it happened, and I'm trying to find some best guesses to lay out before we get to the Cambrian Explosion.
And it's also partly because there's been a lot of distractions in real life. Hopefully, those are past.
