Jackson Wheat - Cambrian "Explosion" - What a science communicator sounds like

Past couple years I've noticed and watched a number of Jackson Wheat's videos and have consistently been impressed.  Now it turns out that he's provided the best introduction to the Cambrian Period for my purposes.  

He overcame my preference for highlighting genuine scientists in this series because he does such a nice job of confronting the ID challenge up front.  I didn't find much bio except that he looks to be a surprisingly young guy.  The man holds a lot of promise, I wish him well.  He also shows us what descriptions should look like, loaded with reference to sources.   Below the fold I share a series of key screen shots, followed by Wheat's detailed list of sources with links.

If I had more time, I'd love to do a little more commentary on his content since the two videos certainly have plenty worth discussing, but other matters are crowding me and I need to keep this going.  He does toss in a short loud introduction loop, but after that it's smooth sailing as Jackson succinctly summarizes the Cambrian "Explosion" - enjoy.
