Happy Valentine's Day everyone!  Today we talk laurel and geckos and then settle in for our longest episode yet.  The reason?  For explosions! More specifically the Cambrian Explosion.  This episode describes the billions of years leading up to the Cambrian.  We cover the formation of earth, first signs of life, an oxygen crisis and everything in between.  This is just a cursory glance at what happened on our planet, so we can understand the lead up to the Cambrian Explosion, which we'll be talking about next week.  This format is something new for us so if you have any comments hit us up on twitter, [email protected], or leave a review wherever you listen to podcasts.  As always, the information shared from the episode will be linked at podcastbraindump.com Thanks to everyone out there for the support, we'll keep getting bigger and better.  Enjoy!
