The Explosion That Started It All

IllustrationIf you think real hard back to your school-days, you might remember something called the Cambrian Explosion. 

This event happened around 541 million years ago and was when most major animals started to appear in the fossil record. 

It was long thought that this was the first explosion of life on our planet, but a discovery in 1946 eventually changed this hypothesis. 

As it turns out, life before the Cambrian Explosion was more diverse than anyone had previously imagined. 

This entertaining and interesting video by PBS Eons will give you all the juicy details about this revolutionary discovery.
