@Sheril Great to hear! Doug Emlen and I are just wrapping up the last chapter for the next edition. Got a chance to slip in the latest Homo naledi stuff before the deadline.

@Carl_Zimmer It’s so well done. I’m taking an evolution course to get up to speed & flying through 3 chapters a week. Thoroughly enjoying it. The examples are excellent.
