Question

Is the junk DNA in human is it totally 'junk', if so why evolution maintaining it, doing such is not the style of evolutionary mechanism?

Answer 1

Eh, it's not really junk DNA.

Here, I'll post a link:
http://www.disinfo.com/2012/09/junk-dna-not-so-junky-after-all/

It's a very short article. Just a heads-up. But it has recently been discovered that this "junk DNA" could actually have a great influence on our resistance to disease.

I honestly don't know much about it. But it sounds interesting.

And if it's true, then I suppose we know why evolution has carried it.

Answer 2

I heard about that recently as well, @InYourHead.

Generally, if something has been maintained in a mostly unchanged state, it probably serves some sort of purpose.

Answer 3

Yeah, what you say makes a lot of sense to me.

Answer 4

just like Large Hadron Collider experiment in physics, in biology there happened (and continuing) one huge experiment, known as Encyclopedia of DNA Elements (ENCODE) project coordinated by The ENCODE Project Consortium. see the article here

So the junk is not really junk, remaining will not work properly without this junk..

Answer 5

I read that article as well. Huge step in the identification of "junk" DNA....which was a pretty stupid idea to begin with honestly. If its there, it is being used in one way or another.

Answer 6

we still don't know the regulation of some inborn characters like behavioral patterns, some type of inborn abilities etc.. the study of junk DNA will give the regulation of those.. some times science discoveries change even the root of preexisting hypothesizes. Advanced studies in junk may give answer to somany problems.. even main reason for malignancies.. etc. There is hope bcz we don't know much about it.. we will get the answers so soon sure
