DNA changes over a long period of time by different factors such as the temperature. For example, During the ice age, the organisms have tough skin, heavy fur to keep their body temperature warm. Then the earth warmed up so the these organisms no longer need the heavy fur to keep warm. Their children's children began to evolve to have less fur in order to not die of heat. The organism changes when its surroundings/environment change. Evolution is needed for the organisms to adapt and survive to the current living conditions presented upon them.

The reason you aren't getting a good answer to your question is that to understand evolution, you have to understand DNA. Unfortunately, DNA is complex enough that even I don't know exactly how it works.
Here's a one idea: Let's say that a species has a gene to grow a neck three inches long. Somehow a member of that species gets injured or something and manages to have two copies of that gene, so it grows a neck six inches long. Centuries later another mutation happens and it gets three copies of the gene so it has a neck nine inches long. Now your horse is a giraffe.
So, how does a fish grow hands? To make a fin, a fish has a bunch of genes. After a while it might get mutations so that the fin lets longer like and arm, and the fin separates to make finger.
We don't know the exact process for sure since we haven't witnessed most of it in person. All we've done is piece together fossil records.

A changing environment results in changing creatures. A fish might start out with a special or mutant fin that gives the fish an advantage over other fish. In theory evolution would reach a point of perfection were mutations were no longer advantageous if the environment remained constant.

It just does who nows the DNA suffers all kind of processes, in does processes some are lost some are added.
In a more innatural way everyting that changes your body chemical properties, pH, current pass, EM waves, can microscopically desviate an molecule from it's place giving another configuration to DNA, ...
radiactivity works with much more intensity because it afects the reproductibility of the cells

THE ORGANISM CHANGES ITSELF TO THE ADAPTATIONS.
if you are living in a place which is hot, and when you move to a cold place,You feel first hard. But when you stay there for a long time your body adopts it and this is a little kind of evolution.
From the above e.g., the DNA is not changing at first.First your body adopting that,
The evolution don't takes place at a little time(except body adopting)it takes long time to change its DNA(millions of years)

An individual does not evolve, or "grow legs and arms out of its fins", a population evolves over millions of years. Small random changes are "selected" if they provide an advantage for an organism. In this case they are passed on to offspring. Everything changes. The entire planet is in constant change this causes advantageous genetic change to be in constant flux.

i dont know. but we are all pluripotentiated. we all started as one. one is a metaphore for allness, undivided, at one ness, or godhead. once division into two takes place things become opposites or the direct mirror images of each other. things become us and not us, eventually resulting in consciousness due to seperation. with seperation come the crisis of identity and purpose. what is and isnt. we forget that we still are and always will be, but other is different and not exactly us because when there is more than one, there is time. there is sequence. but it is illusion because there is still only now. all past present and future exist only in the vast eternity of nowness. but seperation chops nowness into segments and illusion. maya. thesingle cell of the amoeba throws pseudopods of cytoplasmic reticulum to engulf another, creating a mouth, and later an anus. soon the hole that is outside of us we create within us, as a gastric system, a tunnel which we pass the universe through, sifting it. siphoning it. and wings are fins, not different. propulsion units, flagelation, cilliation, tentaacles, stingers, filaments, flappers, tails legs, pseudopods, anchors, all the same. multiflurous expressions of diversity, eating and being eaten, consciousness and asleep. in the vortex and vortex making. we are becomming.
my question is how to touch the human mind next to mine so finely, so intimately, that we know each other and connect, synaptically, and inspiring the highest knowledge we lift each other off this earthly realm, levitating in an evolution beyond the murder of unconsciousness. i await the feast of gods, where golden sunshine is the food, and compassion the motivation for creation of a new universe yet unseen by any telescope. a devine ordering so delicate and pristine, that gasps of air are tearfully weeping down the cheeks of galactic arms, and a dance of light years shouts the joyfullness of connection finally arrived. the building of our heaven, once a premonition, is filling the void of the heart of darkness, and exploding with the joy of a supernova. the universe, expanding at an ever increasing rate, races to keep up with consciousness. an i, who am you in another skin, will rejoin each other in a fusion of delightful treasures. telling all the stories of eternity in an endless poems chant.

He it is Who created the heavens and the earth in six Days and then Istawa (rose over) the Throne (in a manner that suits His Majesty). He knows what goes into the earth and what comes forth from it, what descends from the heaven and what ascends thereto. And He is with you (by His Knowledge) wheresoever you may be. And Allah is the All-Seer of what you do

with the above saying.the theory of evolution is completly wrong and baseless.
1)how can something come to exsistence from nothing?
2)If man was evolved from ape,then from where were ape evolved from?
3)if man evolved from ape then now something has to evolve from man atleast some small,minute thing atleast?

Some scientist believe that DNA mutations accord and actually help the organisms survive. however, anyone who does enough research for them selvs and doesn't just take some one elses word for it will see that there is design.

Well, to change into a different species is doubtful. People have become larger, but they are still people. Flowers change colors, but they are still flowers. Fish are still fish, etc., etc....
