Atheist how are useful organs developed, evolution makes no sence?

Question

How are all of our useful organs developed? How would one survive if our organs where in some transitional stage? How useful would half a lung, heart, kidney or even an eye be to us? How does such extremely complex organs evolve? Isn't this a wonderful sign of creation? I would prefer a smart and logical awswer, keeping in mind the complexity of these organs...

Answer 1

No, it's not a sign of creation... It's a sign of your own ignorance towards the evolutionary process.

Answer 2

First off, it is pretty apparent you have no idea what evolution is or how it works. Even if evolution wasn't a fact (which it is), just because we have complex organs does NOT indicate there was a creator.

In fact, it is pretty clear there was NO "intelligent" design behind the human body. If there were:

1. What is the appendix for? Why would that be "created" with no purpose?
2. Why does the optic nerve come out of the FRONT of the eye, thereby causing a blind spot in every human (doesn't sound like too intelligent a design, does it)?
3. Why do air and food go down the same tube? If food gets stuck in the throat, you die because you cannot breathe. Seems like there was zero intelligence behind that design.

I could go on and on, but really, if you spend 10 minutes doing a search on the internet about evolutionary theory (and stop living a fairy tale) you should be able to comprehend the elegance of evolution.

Answer 3

My advice is to read up on it and ask questions in an appropriate forum. Having said that, here's one example:

Simpler multicellular organisms such as arthropods and worms have a much simpler circulatory system than ours - basically just an open-ended muscular tube which contracts slowly and rhythmically, pumping interstitial fluid (the fluid surrounding the cells) through the body. The really interesting point is that the genes which control the development of this simple tube in arthropods are the *very same genes* which control the development of the human heart. So, it's clear that both systems share a common evolutionary origin - it's just that the mammalian circulatory system has evolved further variations and become more complex along the way.

So that's how complex organs evolve - by very slow incremental changes from very simple systems over many millions of years.

Answer 4

Animals did not need lungs or kidneys in the water; they only became necessary during the invasion of land. Some amphibians can change waste and oxygen through their skin when they are in water. Incomplete organs only allowed limited time on land.

The earthworm "heart" is just a series of 5 muscular bands. In is sufficient for a creature that size. The size of an organism would be limited by the development of the heart.

Answer 5

Well when the single-celled organisms started to make multi-celled organisms, the different cells then made more specialized "organs" (think of how a zygote develops) So eventually they made them in the way they are now, in any species, I hope that I answered satisfactory. Also, if having a complex organ (such as what you suggested) is proof of creation, what about the useless organs that we have, such as the appendix? The only thing that we have use for it is to digest raw meat (at least from what most scientists say) why did God make a useless organ then? Hope I helped!

Answer 6

We ARE in a transitional stage. Every living thing on Earth is. Transitional simply means we are constanly evolving into the next species, although it doesn't happen over night. You don't even notice any differences in your lifetime. Complex organs evolve because there is (or was) some kind of need for them. Ever heard of "survival of the fittest"? That is another way of saying "natural selection." Natural selection is the basic concept that useful mutations, or differences among the population, will allow that particular organism to reproduce more sucessfully, thus increasing their genes in the entire gene pool. Over great amounts of time, those genes will get adopted more and more as organisms reproduce.

Its a lot more complicated than that, but everything you could possibly want to know is here: http://www.talkorigins.org

Answer 7

Even half a lung or half a heart would be better than no heart at all. Or rather, a partially formed lung or a partially formed heart.

Fish that crawl up onto land have a much simpler respiratory system than mammals - a half-developed lung, if you will. Wormy life has much simpler hearts than mammals. These creatures are thought to be similar to other, extinct animals on the evolutionary chain of development.

Answer 8

OK, I understand the questioner means something else when he says half a lung, heart, kidney etc. but the answers indicate to me that just because an organ's function is not understood or its removal has no ill effects it means it is vestigeal. Nothing could be further from the truth. I have dealt with appendix elsewhere but similarities among different species DOES NOT constitute proof that one species is derived from the other. That's a load of speculation which cannot be proven scientifically.

Answer 9

Obviously, we never had any time had "half a heart" or any of those things. Take a look at a simpler species. Bacteria needs no heart. Most insects breathe without the use of lungs. Certain species of fish have underdeveloped eyes that serve them just fine. Why do some birds have useless wings? Why do we have certain appendages that we have no use for? Why do some animals have bones that give them no advantage?

Please don't let your belief in a god disprove evolution for you. Contrary to misconception, you can believe in both at the same time.

Answer 10

Most of the "problems" of biology, physiologically, were solved before humans existed. Smaller animals, even single celled organisms, developed very simple structures to help them live, compete, and thrive. Evolution is how they developed. No one is claiming that the kidney evolved on the scale that it exists in humans. It was initially something very simple in a very small animal, then it took millions and millions of years to become the complex and species-specific thing it is now.

Answer 11

Think about this. All mammals with a wide variety of items in their diets have an appendix. Bears, raccoons, badgers, etcetera. The appendix helped to digest hard to digest items like small bones, nut shells, and hides. We don't use the appendix anymore and it just sits there inactive, and as such, is proned to infection. That's why it can be removed and not effect digestion. I thought that was interesting when I found out.
