This is a video created by Vox senior editorial producer Joss Fong detailing some of the vestigial traits that help prove that humans evolved over millions of years and not just the last 200 like my middle school science teacher in Alabama tried to teach us. I learned a lot by watching it. Mostly that four minute videos are too long for me but if you skip around nothing makes sense.
Keep going for the video.
Thanks to Dunc, who is one of a kind and didn't evolve from anything, he was just put here like a beautiful vase of flowers.
