It's hard to deny evolution in the presence of insurmountable evidence from thousands of years of archeological records. During this time, countless changes accumulated and led to species' current states. For humans, we can see in the records when our brains expanded in size and when bipedalism began to take hold. Another example of evolution and natural selection is the well-known example of the peppered moths, which evolved to have darker wings that better camouflaged them in the smog.

But within our own bodies, humans can observe traces of evolution that offer indisputable proof of this process. These biological marks take the form of vestigial structures - those that were once useful for our ancestors but no longer have a function for us now. The coccyx, commonly known as the tailbone, is an example of a vestigial structure that has yet to be phased out of our bodies. Watch the video to learn some lesser-known examples of evolution's marks on your own body!
