What Evolution Left Behind
Very interesting read...
Appendix
We all know about this one. You might even know someone who has had it removed. The appendix is a narrow, muscular tube attached to the large intestine. A common misconception is that this organ was used for digesting raw meat. It was actually used in our plant chewing days. It would aid in the digestion of cellulose. As the human diet changed, this organ stopped functioning, as it was no longer used. To be noted though, the appendix is rich with infection-fighting lymphoid cells, which leads some to think it still plays a role in our immune system. If the appendix did have this function, one would tend to believe that its routine removal would cause ill side effects.
Paranasal Sinuses
For as far back as I can remember, my mother always had sinus problems. Sometimes so bad she’d have to lay down just to make the pain bearable. Ironically, the sinus cavity serves little to no purpose for a human. The presence of our sinus cavities however actually do make our heads weigh less. The sinus cavity also adds warmth and moisture to the air we breathe.In animals with an heightened sense of smell (like a dog or cat), the sinus cavities are lined with olfactory tissues. Some scientists believe that our ancestors had a much better sense of smell (our DNA contains broken genes for additional odor receptors) but for some reason we lost that ability. Possibly as man grew more intelligent and our hunting techniques evolved, better ways of hunting emerged without the use the sense of smell.
Vomeronasal Organ
A tiny pit on each side of the septum is lined with non functioning chemo-receptors. They may be all that remains of a once extensive pheromone-detecting ability.Taken from Wikipedia:
Anatomical studies demonstrate that in the vomeronasal organ regresses during fetal development, as is the case with some other mammals, including apes, cetaceans, and some bats. There is no evidence of a neural connection between the organ and the brain in adult humans. Nevertheless, a small pit can be found in the nasal septum of some people, and some researchers have argued that this pit represents a functional vomeronasal organ. Thus, its possible presence in humans remains controversial.
Coccyx (AKA: The Tail Bone)
The coccyx is a set of fused vertebrae at the bottom of the spinal column. This is another useless remain of our ancestral past. It’s all that’s left of our tails, which disappeared from hominids before they began walking upright. The coccyx does serve as somewhat of a shock absorber, though that was not it’s original function.It is true that the coccyx has nine muscles attached to it, such as the muscle that is “necessary” for defecation. It should be noted that the coccyx, if surgically removed, does not cause any apparent health issues.
Extrinsic Ear Muscles
These three muscles most likely made it possible for prehominids to move their ears independently of their heads (again, like a cat or dog). We still have these muscles which is why most people can learn how to wiggle their ears.
Toes
While losing ones toes would cause problems with walking for awhile, we technically only need our big toe as a function to help keep our balance. Our toes were most likey used at one point for grasping on to things and climbing.
Neck Rib
This is a set of cervical ribs commonly thought to be leftovers from the age of reptiles. They still appear in less than 1% (about 1 in 200) of humans, and in rarer cases a person may not just have one but have two neck ribs. Unfortunately, these can cause nerve and artery problems.
Darwin’s Point
Take your finger and run it along the the inner edge of your ear. Near the top you’ll notice a small piece of skin that is almost like a point. If you can’t find it, don’t worry not all humans still carry this. They believe that this may be a remain of a larger shape that helped us focus on distant sounds.
Third Eyelid
Somewhere along the evolutionary journey we actually had a third eye lid, much like you see on a frogs, for example. Humans retain a tiny fold in the inner corner of the eye.
Palmaris Muscle
This muscle (if you have it, only 11% of humans do) is a long and narrow muscle that runs from the elbow to the wrist. It is believed it may have been an important muscle for hanging and climbing. If you ever need reconstructive surgery, this muscle might be harvested for that purpose. Perhaps this should be called a human replacement part.
Subclavius Muscle
This muscle stretches under our shoulder from the first rib to the collarbone. It would still be a useful part if humans still walked on all fours. Not all humans have one and a small number of us actually have two.
Male Nipples
Lactiferous ducts (the lobes of the mammary gland at the tip of the nipple) form well before the the testosterone is released that causes a fetus to be a male. Also, men have mammary tissue that can be stimulated to produce milk.
Wisdom Teeth
If you’re reading this, you’ve probably had your wisdom teeth removed. I had all four of mine pulled when I was in high school. Despite what you think, these teeth weren’t totally useless. Since early humans had to chew a lot of plants (to intake the amount of calories needed to survive) the more teeth the better. Another theory regarding wisdom teeth is that they were replacement teeth that were lost from wear and tear.
Erector Pili (ie. Goosebumps)
These are bundles of smooth muscle fibers that allow animals to puff up their fur to intimidate others. They also served the function of insulation when we had more body hair. While we still retain this ability our lack of body hair makes them useless. Ever get startled and you get goosebumps? Ever see the same thing on other animals? Not as intimidating when you don’t have the hair or fur to puff up.
Body Hair
Most of your body hair serves no function (though some think otherwise). Eyebrows keep sweat from going into your eyes, and male facial hair may play a role in sexual selection. Armpit and pubic hair help deal with moisture but beyond that it does us no good. Your arm and leg hair are just the remains of a once fully covered body of hair.
Thirteenth Rib
While our closest cousins (chimps and gorillas) still retain this extra set of ribs, most humans have 12 ribs. Additionally, about 8% of humans are born with extra ribs.
Male Uterus
While not exactly a evolutionary left over, the remains of the undeveloped female reproductive organ from our prenatal state still remains. This organ hangs off of the male prostate gland but obviously serves no purpose.
Female Vas Deferens
These are a cluster of useless dead-end tubules near the ovaries. Yet another left over from our prenatal existence, these are thought to become sperm ducts in males but develop into the epoophoron in females.

Re: What Evolution Left Behind
I may have that ehhh Darwin's Point. On both ears. In fact, on one ear it seems like I've got two of them.
And of course I've got all the sexy body hair (mostly extreme leg and arm hair) and the wisdom teeth.
So I'm basically a Neanderthal.

Sepi needs to read this...It means his lack of body hair means he's evolved more than us rather than lack of masculinity.But since he's more into Jersey Shore type threads than science this revelation will stay secret to him and he will feel emasculate for the rest of his life

No it does not, but there is a very mysterious big bang though

Neither side fully explains the origins of the Universe. One says it's incomprehensible and the other side says it just always was.

Re: What Evolution Left Behind
A theory is NOT a FACT. A FACT is PROVEN, and it's there for all to see - not debatable, a theory is NOT something everyone might agree on, and thus it can not be A fact - because it's something debatable.
You can prove religion wrong, but you can't prove or disprove the existence of a higher power/creater/God.

Re: What Evolution Left Behind
gravity is a theory but we all know its there. Newtons theories on gravity were valid for centuries and yet they are obsolete in today's world. Einstein's theories risk the same fate if recent scientific discoveries are validated. In short, a theory might provide a reasonable explanation for a certain phenomena but it shouldnt be treated like the truth unless proven.
i personally believe in evolution but i dont think its a complete theory as you can poke many holes in it, yet, i still believe that all living beings change (or evolve) to adapt to certain environmental changes in order to survive.
Humans certainly evolved, and they continue to do so. take the example of the native americans who tend to store fat around their chest and neck to protect their organs from the cold of their environment, while the lack of glucose in their diet makes them more vulnerable to diabetes. This process is called adaptation (or the lack of it) and its the corner stone of the theory of evolution.

Re: What Evolution Left Behind
Zizzle said it clearly. Gravity is one theory we treat as truth without realizing that it is just means to explain the phenomenon.
Evolution as it is is based mostly in imagination and the article provides few facts and are rather hindsight knowledge. Basically fitting the evidence to the theory.
For example, on body hair.
People in hot zones have more body hair than people in cold zones, and far Asians have very little body hair. The whole difference in races gives the theory of evolution a lot of work to do. Newton's laws were accepted as the truth before they were found out by Einstein. Arsitotle's laws were the truth before and they were found out.
Treating the theory of evolution as Religous people treat holy texts makes you in the same boat.
On a mathematical scale, the probability of the theory of evolution is less than the probability of a book being written by the explosion of a printing press. The neo-religious ideas simply makes the creator a director of evolution.
Of course, you did not bother looking up the math or doing some research on it. The fact that many recent noble prize winners and many famous scientists believe in God makes the opinions that whomever believes in God is stupid a stupid opinion.
