You Can Find the Proof of Evolution in Our Own Spare Body Parts: From Third Molars to Vestigial Tails

Look­ing for proof of evo­lu­tion? Per­haps you don’t need to look much beyond your own body. Cre­at­ed by Vox, the video above high­lights the ves­ti­gial body parts and traits we’ve retained from ear­li­er points in our evo­lu­tion­ary his­to­ry. Writes Vox’s Joss Fong:

Ves­ti­gial struc­tures are evo­lu­tion’s left­overs — body parts that, through inher­i­tance, have out­lived the con­text in which they arose. Some of the most delight­ful reminders of the com­mon ances­try we share with oth­er ani­mals, they show that the build­ing blocks of the human body pre­date our species by hun­dreds of mil­lions of years.

For a clos­er look at the mechan­ics of evo­lu­tion, you can spend time with Yale’s open course, Prin­ci­ples of Evo­lu­tion, Ecol­o­gy and Behav­ior, which is part of our col­lec­tion of Free Online Biol­o­gy Cours­es. But if you don’t want to dig ter­ri­bly deep, then start with Carl Sagan’s eight minute ani­mat­ed primer. It’s pet­ty hard to beat.
