Evolutionary biologist and science educator Joe Hanson, the person behind the website / YouTube show It's Okay To Be Smart is currently running a twelve part series "The Twelve Days of Evolution" in which he outlines the evidence for evolution and shows how evolutionary biology allows us to understand our natural world. Currently, he is up to day eight. As each episode is released, I will be updating it here. Definitely one to share with those who are time-poor or on the run.
