This is something I get allot, "If God created us, why do we have vestigial organs? Shouldn't everything be perfect?" Well yes, God created us and every little thing we have supports our body in some way. This is often used as an evolutionist argument, arts that are left behind from our ancestors.
A few years ago, there was a list containing all the "vestiagial" organs in our body, I think it included about 80. That list has been narrowed down, to 0. There are a few that were not mentioned that are mentioned today, but its still not vestigial. I will list a bunch of vestigial organs from various websites, I will explain what the organ is, if I can, what it came from, and then explain why it is not vestigial.
Plica semilunaris
Also known as the third eyelid in some cases.
What is it?
The plica semilunaris is a small fold of bulbar conjunctiva on the medial canthus of the eye. A non biology version would be, that little pinkish triangle thingy at the point of your eyes closest to your nose.
Here is a picture of one:
Where did it come from?
It is believed that this came from reptiles or birds. They use it allot, some other animals like cats and chickens. It is believed that we didn't use it, so it shrunk, and never fell off.What it is used for
Now something I'd like to point out, just because it seems to be the same thing doesn't mean it is the same thing. Look at us and whales, we have 2 bones in our wrist and whales have bones with the same names close to their tail, yet to do completely different things. So it has the same name, but that means absolutely nothing they are not the same. Now the plica semilunaris is definatly not vestigial. I thought most people should be able to figure it out, but since it is used as examples... What happens if you cry? Where does the tears go? Straight to your plica semilunaris and it slips right off! What happens if you get sand in your eye? It hurts or burns, blink a little and you will notice that the dirt is moving closer and closer to the plica semilunaris, once its there its much easier to get it out! The plica semilunaris helps to keep your eyes clean and slippery.
Take contact lenses for example. Have you ever seen someone fall asleep with contact lenses in their eyes? I have, when they wake up their eyes are really really dry. The contact lenses blocks whatever the plica semilunaris wants to do to make the eye slippery, since you have contact lenses in it can't perform its job, making your eyes dried up when you wake up in the morning.
Body hair
I'm sure you all know what that is!
Where did it come from?
It is believed that this came from chimps, but I'm sure you knew that.
What is it used for?
Hair is used for things other than warmth. Hair intensifies the sense of touch, when they are moved or bent. The amount of hair is determined by your genes, not everyone has the same amount of hair everywhere, there are allot of other things that affect your hair growth such as androgens. I'm not going to go into the biology of it. Hair is mostly used for body heat.
Sinuses
What is it?
Well I thought this wasn't really worth to be on the list, but hey, I'm just reading from the lists and then replying. Sinuses are air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face.
What is it used for?
Well, even some evolutionists agree that sinuses are not vestigial, allot of debates have gone on about it, but it is suggested that the sinuses's functions could be:
- Decreasing the relative weight of the front of the skull, and especially the bones of the face. The shape of the facial bones is important, as a point of origin and insertion for the muscles of facial expression.
- Increasing resonance of the voice.
- Providing a buffer against blows to the face.
- Insulating sensitive structures like dental roots and eyes from rapid temperature fluctuations in the nasal cavity.
- Humidifying and heating of inhaled air because of slow air turnover in this region.
What is it?
Adenoids are a mass of lymphoid tissue situated at the very back of the nose, in the roof of the nasopharynx, where the nose blends into the mouth.
What is it used for?
It is used to trap and destroy pathogens in the air that enter the nasopharynx.
If you have yours removed, not a problem, you might just get a few diseases others don't get.
Tonsils
What is it?
The tonsils are areas of lymphoid tissue on either side of the throat.
What is it used for?
Well these two small glands in the back of your throat help protect you against infections.
Coccyx
Also referred to as a tail bone.
What is it?
It is the final segment of the human vertebral column.
You can find it right there:
What is it used for?
Scientists have found that important muscles attach to those bones. Without those muscles, your pelvic organs would collapse Without them you could not have a bowel movement, nor could you walk or sit upright. Or go to the bathroom if you really have to go after eating allot!
Goose bumps
What is it?
Are the bumps on a person's skin at the base of body hairs which may involuntarily develop when a person is cold or experiences strong emotions such as fear or awe.
What is it used for?
Goose bumps are caused by muscle contractions. These force oil into the follicle and onto the skin. This traps air around the surface of the skin and provides added insulation.
Appendix
What is it?
It is a blind-ended tube connected to the cecum, from which it develops embryologically.
What is it used for?
Science recently discovered that man needs this organ. It helps protect you from gastrointestinal problems in the lower ascending colon. It also fights infection. The problem is they say if something can be cut out and you can still live fine then its vestigial. Thats not how it works, cut off an arm, you can still live fine, does that make the arm vestigial? Same with your eyes, toes, fingers, everything you have has a function, just because you can live perfectly without them doesn't mean they are not needed.
Seriously the list just goes on and on and on, even though it mostly has a logical explanation people still choose to use it as arguments. Now we hit a problem for evolutionists, why arn't there any vestigial organs? See what has just happened there? Evolutionists ask questions, which are fine, but when we answer them, the same question is asked to them, but the opposite. According to evolution we should have a bunch of vestigial organs.
Other questions like this is, "What about the Geologic column?" then this is easily explained and the faults are pointed out in the evolutionists point of view, then we might ask why it looks like that. For example, why are there no erosion marks with the layers, if it formed over millions of years, don't you think it would rain once or twice? Or "How do you explain dinosaurs?", then after my explanation I can ask, why are human and dino footprints found on the same place, why are dino's mentioned and described in the bible, why did egyptians etc. know allot about dinosaurs?
So yea, its something to think about. Thats all for this topic.
