You might hear the NERD bells go off in your head when you saw this article, but I still thought it was extremely interesting. Here are parts of your body that you actually don’t need. Check out point 13. LOL.
1. VOMERONASAL ORGAN (VNO), or Jacobson’s organ: a tiny hole on each side of the nasal bridge that is considered to be connected to nonfunctional chemical receptors. Could be all that is left from our once great ability to detect pheromones.
2. EXTRINSIC EAR MUSCLES: These three muscles most likely made it possible for our ancestors to move their ears independently of their heads, as rabbits and dogs do. We still have them, which is why most people can learn to wiggle their ears.
3. WISDOM TEETH: Early humans had to chew a lot of plants to get enough calories to survive, making another row of molars helpful, but unless you chew a lot of branches, these will eventually come out in a painful procedure. Only about 5 percent of the population has a healthy set of these third molars.
4. NECK RIB: A set of cervical ribs—possibly leftovers from the age of reptiles, still appear in less than 1 percent of the population. They often cause nerve and artery problems.
5. THIRD EYELID: A common ancestor of birds and mammals may have had a membrane for protecting the eye and sweeping out debris. Humans retain only a tiny fold in the inner corner of the eye, exactly there where you always catch a spec of dust or debris.
6. DARWIN’S POINT: A small folded point of skin toward the top of each ear is occasionally found in modern humans. It may be a remnant of a larger shape that helped focus distant sounds.
7. SUBCLAVIUS MUSCLE: This small muscle stretching under the shoulder from the first rib to the collarbone would be useful if humans still walked on all fours. Some people have one, some have none, and a few have two.
8. PALMARIS MUSCLE: This long, narrow muscle runs from the elbow to the wrist and is missing in 11 percent of modern humans. It may once have been important for hanging and climbing. Surgeons harvest it for reconstructive surgery.
9. MALE NIPPLES: Lactiferous ducts form well before testosterone causes sex differentiation in a fetus. Men have mammary tissue that can be stimulated to produce milk. This just makes me angry; I’ve been spending a fortune on milk all these years! I’ll have to test this tomorrow with my Special K.
10. ERECTOR PILI: Bundles of smooth muscle fibers allow animals to puff up their fur for insulation or to intimidate others. Humans retain this ability (goose bumps are the indicator) but have obviously lost most of the fur.
11. APPENDIX: This narrow, muscular tube attached to the large intestine served as a special area to digest cellulose when the human diet consisted more of plant matter than animal protein. It also produces some white blood cells. Annually, more than 300,000 Americans have an appendectomy.
12. BODY HAIR: Brows help keep sweat from the eyes, and male facial hair may play a role in sexual selection, but apparently most of the hair left on the human body serves no function.
13. THIRTEENTH RIB: Our closest cousins, chimpanzees and gorillas, have an extra set of ribs. Most of us have 12, but 8 percent of adults have the extras.
14. PLANTARIS MUSCLE: Often mistaken for a nerve by freshman medical students, the muscle was useful to other primates for grasping with their feet. It has disappeared altogether in 9 percent of the population.
15. MALE UTERUS: A remnant of an undeveloped female reproductive organ hangs off the male prostate gland.
16. FIFTH TOE: Lesser apes use all their toes for grasping or clinging to branches. Humans need mainly the big toe for balance while walking upright, the other four are for holding when you slam them on a coffee table at night!
17. FEMALE VAS DEFERENS: What might become sperm ducts in males become the epoophoron in females, a cluster of useless dead-end tubules near the ovaries.
18. PYRAMIDALIS MUSCLE: More than 20 percent of us lack this tiny, triangular pouch-like muscle that attaches to the pubic bone. It may be a relic from pouched marsupials.
19. COCCYX: These fused vertebrae are all that’s left of the tail that most mammals still use for balance and communication. Our hominid ancestors lost the need for a tail before they began walking upright. All they’re good for now is give us painful falls on the butt.
20. PARANASAL SINUSES: The nasal sinuses of our early ancestors may have been lined with odor receptors that gave a heightened sense of smell, which aided survival. No one knows why we retain these perhaps troublesome mucus-lined cavities, except to make the head lighter and to warm and moisten the air we breathe.

very interesting, thanks
I was actually born without wisdom teeth. Good to know I don’t need them.
Just because we don’t know what they do don’t mean we don’t need them.
ONE of the theory of evolution’s important deceptions is its claim regarding “vestigial organs.” Evolutionists claim that some organs in living things lose their original function over time, and that such organs then disappear. Taking that as a starting point, they then try to send out the message, “If the living body had really been created, it would have no functionless organs in it.”Evolutionist publications at the start of the twentieth century announced that the human body contained up to a hundred organs that no longer served any purpose, including the appendix, the coccyx, the tonsils, the pineal gland, the external ear, the thymus, and wisdom teeth. However, the decades that followed saw major advances in medical science. Our knowledge of the organs and systems in the human body increased. As a result of this, it was seen that the idea of vestigial organs was just a superstition. The long list drawn up by evolutionists rapidly shrank. It was discovered that the thymus is an organ which produces important immune system cells, and that the pineal gland is responsible for the production of important hormones. It also emerged that the coccyx supports the bones around the pelvis, and that the external ear plays an important role in identifying where sounds come from. In short, it emerged that ignorance was the only foundation on which the idea of “vestigial organs” rested. Modern science has many times demonstrated the error of the concept of such organs. Yet some evolutionists still try to make use of this claim. Although medical science has proved that almost all of the organs that evolutionists claim are vestigial actually serve a purpose, evolutionary speculation still surrounds one or two organs. The most noteworthy of these is our wisdom teeth.
Evolutionists have taught that humans evolved from ape-like ancestors that possessed larger jaws and teeth than us. In the process of evolution the jaw has become smaller, allowing less room for the third molars and causing numerous dental problems. Our better understanding of the complex teeth-jaw relationship has revealed this explanation is far too simplistic. Research now indicates that the reasons for most third molar problems today are not due to evolutionary changes but other reasons. These reasons include a change from a coarse abrasive diet to a soft western diet, lack of proper dental care, and genetic factors. Common past dental practice was a tendency to routinely remove wisdom teeth. Recent empirical research has concluded that this practice is unwise. Third molars in general should be left alone unless a problem develops and then they should be treated as any other teeth. At times removal is required, but appropriate efforts to deal with problem teeth should be implemented before resorting to their extraction.
The conclusion that a smaller jaw cannot contain the large teeth we inherited from our ancestors, and consequently wisdom teeth are not needed, has recently been challenged on several fronts. Macho and Moggi-Cecchi[Macho, G.A. and Moggi-Cecchi, J., 1992. Reduction of maxillary molars in Homo sapiens sapiens; a different perspective. American Journal of Physical Anthropology, 87(2):151–159.] concluded that compared to other primates the third molars are the smallest in Homo sapiens. Further, if the third molars are forced to develop in a more restricted space ‘they tend to be smaller than anterior’ teeth and ‘in humans this reduction often leads to agenesis [failure of an organ to develop] of the third molars.[ Macho and Moggi-Cecchi, Ref. 17, p. 156.]Dental crowding in whites ‘seems more related to smaller alveolar space than to smaller jaws overall or to larger teeth.’[Corruccini, R., 1991. Anthropological aspects of orofacial and occlusal variations and anomalies. In: Advances in Dental Anthropology, Chapter 17. Kelley, M.A. and Larson, C.S. (eds), Wiley-Liss, New York, p. 308.]Furthermore, in an extensive study of aberrant maxillary third molars, Taylor found a lack of evidence for a genetic trend towards elimination of the third molar from human dentition as assumed by many evolutionists.[ Taylor, M.S., 1982. Aberrant maxillary third molars; morphology and developmental relations. In: Kurtèn (ed.), Ref. 5, pp. 64–74.]
It is now widely acknowledged day that these teeth are not rudimentary or vestigial: they aid in chewing our food as do all of our other 28 teeth. The outdated vestigial organ conclusion, though, has influenced the extraction of billions of teeth, the removal of many which may have been unnecessary according to current research[Leonard, M.S., 1992. Removing third molars: a review for the general practitioner. Journal of the American Dental Association, 123(2):77–82.]

Except to MALE NIPPLES!
THAT IS FUNNNNNNYYYY!!!!!!!
LOL
CANT STOP LAUGHING!
