On the 12th of February it is International Darwin Day. A great day to remember what Charles Darwin did for Science in general and Biology in particular. Thanks to his research and dedication we have a much better understanding of why life is shaped as it is throughout history of time. 

And what better way to celebrate this with a parody done by the brilliant artist A Capella Science in which he explains in the most awesome way the field of Evolutionary Developmental Biology.

By the way, check out the other videos he's made on for example Gravitational Waves or the history of Exoplanets.
