Very rarely, human babies are born with what appear to be tails. These are oftentimes caused by an elongated tailbone, or coccyx. These tails are surgically removed and do not usually pose a risk to the child’s health. However, why would humans even have a coccyx in the first place, if we do not have tails? Explain the significance of a coccyx and why humans have it, as well as what type of structure it is and where it comes from. In addition, identify another similar structure in humans and explain its evolutionary history. (Use words such as: vestigial structures, evolution, function, evolutionary remnant)
