I just stumbled upon this cartoon for the first time today and I’m totally blown away. Sure, there are some things that could be explained better. There are a couple of moments when the illustrations could be a bit more accurate. But, overall, it’s a very good summary of the basic elements of evolution and pretty funny. (I wish I had made this!)
Have a watch and enjoy.
also, check out Kurzgesagt’s other animations on the Big Bang Theory, et al.
