Body hair, for example, is only a by-product of a necessity in years past. We already have sweat, skin and clothing to help regulate our body temperatures.
Wisdom Teeth. Aside from being a nuisance and very painful to remove, wisdom teeth provide no benefit to human beings.
Coccyx.The tail bone or coccyx is a vertebrae that serves as a reminder that we, or rather our ancestors, once roamed the earth with tails.
Auricular Muscles. This group of muscles surrounds the outer ear and another one of those that have not been in use for centuries.If you’re wondering what it’s for, it’s the muscles that allow animals and humans to swivel their ears to wherever sound is coming from.
Plica Semilunaris. While it is not exactly necessary, the third eyelid does serve its purpose as it sweeps debris away from the eye.
Appendix. Experts claim that it does have some uses to the human body, but there’s yet to be enough proof for that.
There is, however, enough proof to show that the Appendix has overstayed its welcome to the human body and is one of the most useless organs in the human body.
Vomeronasal Organ. Often found in amphibians, reptiles and other mammals, this organ’s function is to detect chemicals. In the case of humans, it’s to smell pheromones. Unfortunately, this “useful” organ doesn’t seem to work.
Darwin’s Point. How this happened and why this is so remains unclear, even up until today.
What we’re sure of, however, is that the human body can certainly do without it.
Male Nipples. All human beings, male or female, develop nipples even before the development of the reproductive organs.
Unfortunately, this also means that men, who have no use for nipples, will grow them just for the heck of it.
Erector Pili. These tiny muscles are the reason why we have goosebumps. Why we have goosebumps and what purpose it serves, however, is still somewhat of a mystery.
