Are there any neurological factors for evolving?

Postby hitmobi » Sun Mar 20, 2011 12:24 am

Hey!

I hope that this is not a dumb question. I tried to study evolution for some time now but i still have a couple of questions. I tried to search for the answer but it's quite hard to find it.

So here goes:
I understand that evolution occurs because of mutation and natural selection. It really seems hard for me to grasp the whole concept. For example : I understand that organisms developed photon-sensitive cells a long time ago and those later "became" what we now call eyes. But how did an organism develop (for example) muscles to control the lens of the eye just at the right place ? The confusion for me comes from the fact that cells "know" where to develop themselves.

So my question is: Are there any other reasons for evolving beside mutation and natural selection? Maybe what we "feel" with our senses make changes in the DNA or something? Or maybe i just didn't understand mutation and natural selection well enough.

If someone could just clarify this point i would be really happy. Thanks!

PS. If i made a lot of spelling errors, i am sorry.

That is very interesting, it almost sounds like our eye was designed that way, rather than having evolved randomly. Almost like it was created that way. My questions are how did evolution make everything in our body so perfectly, and complexly? Why didn't evolution somehow mess up our eye, or some other part of our body? How can evolution be that exact and precise? One mistake, could have made the human race go extinct. There are trillions of things, that could have gone wrong, but somehow evolution managed not to do any of them. Is that what all of you guys are saying?

...what?

I don't understand. Are you implying that a supernatural being is responsible for placing every cell as they are? I don't even know which supernatural being are you talking about... Is it the god of christianity? Allah? Vishnu? Or is it someone else from the thousands to choose from?

Please stick to your "earth is flat" and "you can cure leprosy by killing birds" theories..

Already got the answer.

Yes, there are other factors. Factors like Epigenetics and Cis-regulation.

To Jonl1408:

Sry, but you are a moron. As i was reading your "evidence" i counted the arguments i could easily refute with my limited knowledge and i came up with 13 of them. All of which not accepting would lead you to deny modern science.

As i thought about writing them .... i realized that nothing i could say would ever make you think rationally so i'm not going to even try.

Let's keep it civil, hitmobi. Name-calling isn't particularly rational either.

Evolution DID mess up our eyes - the photoreceptors point backwards, the light has to pass through many layers of infrastructure to reach the receptors, there are necessary blind spots close to the center of the field, the base system default is "on" when it's off.

If you were an octopus, you could make a much better case for design. They've got much more "logical" systems than ours.

But you'd still be wrong.

I am implying that the God of the Bible, created everything.
@hitmobi
If you believe that you can disprove them, then please go ahead, if you can come up with proof, that they are wrong, then I will acknowledge them as wrong.

If the god of the bible created everything as it is now, he/she/it would be drummed out of the engineers union for incompetence. Only an imperfect mechanism like evolution can explain why there are so many crazy flaws in living things.
