 WHY has life evolved?

We have already discussed whether the theory of evolution is true or not. I know there are still a few silly people out there who refuse to accept the obvious, but this question is for the evolutionists out there.
We believe life started as a microscopic, single-celled organism somewhere out in the vastness of the ocean during an inconceivably long time ago.
But why did life not stop there?
What encouraged it to develop further into increasingly more complex organisms and life-forms? Why did life evolve to come onto land? Why did life evolve into plants and animals? Why did life bother to evolve into humans, whose big brains are a threat to all other life on this planet?
Essentially, as the subject says, why has life evolved?
Have fun!

Now, I really don't want to insult you, but this is exactly what I was talking about a few threads back when I was saying that some people who "believe" in the theory of evolution don't even really understand it and know what it means.
Evolution is not about things improving, or increasing in size. It's about random changes, and survival. DNA is delicate, when it's being replicated, there are bound to be flaws, it will change from the original with each copy. This is mutation. When one of these random mutations actually improves the organisms ability to survive, then it thrives, expands, and spreads itself. Billions upon billions of mutations eventually lead to multi-celled organisms... then digestive systems, and muscles, and limbs, eyes, ears.... and so on.

The Theory of Evolution is quite flawed. It states that species evolved by random, individual mutations. That is ridiculous. If mutations where random, than how do you explain something like a stickbug, or butterfly with patterns that are meant to look like eyes to the predator. What about symbiosis? Giraffes did not randomly grow a long neck, and then discover they could eat the trees. It grew a long neck so it could eat from the trees.

You should thank me for not being as condescending as I could be. Your questions are very simple to answer. You should try to understand the theory before you decide not to believe it, smart guy.
The Theory of Evolution is quite flawed. It states that species evolved by random, individual mutations. That is ridiculous. If mutations where random, than how do you explain something like a stickbug, or butterfly with patterns that are meant to look like eyes to the predator.
Stickbugs exist because they look like sticks. The precursors to stick bugs mutated randomly over thousands of years to look like tons of different things. There was probably a flashing beacon bug, a bug shaped like a lighthouse (with light), a hamburger-shaped bug, a bright red bug in a green field, a bug who stank in just the right way that a lizard could smell it from a mile away, but SURPRISE they all got eaten and failed to stabilize into a species. Of course, the bug who was shaped and coloured like a stick blended in with its surroundings: sticks! Thus, predators were unable to find them to eat and so the bug shaped like a stick mated with another of its species who DIDn't look like a stick, their babies sorta looked like sticks, and so on and so on until all the insects shaped anything like a stick survived and all the other ones got eaten.
As for butterflies, there once was a butterfly with plain red wings who gave birth to a mutated litter of caterpillars who, when in butterfly form, produced wings with the words "EAT ME" whoops unlucky mutation they all died, but the camouflage butterflies survived. There ya go.
Oh, and girrafes? Well, once upon a time there was a short little pig-like antelope. It ate shrubs. Then one day a plague killed all the shrubs, or maybe another shrub-eating animal moved in and ate all the shrubs. Most of the pig antelopes died, but a few were a little taller so they could eat at young trees. Then a young-tree eater moved in and ate all the young trees. Almost all the slightly taller pig antelopes died, except a few were tall enough to eat the foliage from slightly larger trees, and the the slightly larger tree-eaters moved in.... See where I'm going?

Hey has anybody heard about how there's a gene we have who's purpose is to create mutations? I haven't come across this before, I've only heard someone say it.

Few thing are facts, but there are many things that we can logically say are true (although all or many of them may not be). The "laws" that govern matter where also "facts", but they were proven to be untrue. Evolution as a word is a fact, but Evolution in the sense of species evolving from random mutations is quite likely a crock of shit.

That ridiculous. You have a terrible misunderstanding of mutations, and how they are stated in the theory of evolution. First of all, there is not just one species of bugs. A bug could that looks like a stick could not be born from a bug that belonged to a species of bugs that didn't resemble sticks. Mutations don't occur that quickly. If one bug resembles a stick, then all other in its species will resemble sticks. Although the evolution is theoretically possible, it is highly, highly unlikely. The Theory of Evolution leaves out the idea that organisms can have a subconcious interaction with there enviroment. I believe that the stickbug evolved to look like a stick, because its enviroment was filled with sticks. How does a stickbug know to act like a stick, it obviously cannot see itself, or know that it looks just like a stick, yet stickbugs will consistantly imitate a twig.

Read this, it'll make evolution alot more sensible.
I am not debating the exsistence of evolution, or the fact that one species developed from another. I am debating the theoretical mechanics of evolution, and the Evolutionist view, as well as the origin of life. I simply saying that life and evolution where not random occurances.

This is true.
I do agree with Remy thow, it seems a stick bug wouldn't just randomly evolve into a stick.

I agree with most everyone on this thread that evolution occurs and that only "silly" people would dispute the evidence.  But I do question if evolution is a result of random mutation alone. Does the body have the ability to adapt to its surroundings without random mutation?
For example, if we participate in athletics, our body adjusts and becomes stronger. If we spend a lot of time in the sun, our body adjusts and becomes tanner. If we come across a new disease, our body remembers it and we become immune to a 2nd occurence. If we practice holding our breath, our body adjusts and we can do it longer the next time, etc. etc. etc...
Why doesn't the body simply make ALL of us strong, tan, etc. right from the start? Why does it only adjust in response to our environment? Is the body capable of adjusting to new experiences that it has never been exposed to before? What if a group of people decided to spend 8 hours a day swimming, would their bodies somehow change to make swimming easier for them? If their offspring were to swim 8 hours per day, and then their offspring too, would they all eventually start to grow webbed hands and feet? Or would that come from random mutation alone?
I don't know the answer, but it seems to me that the body DOES have the ability to adjust to its surroundings. In the giraffe example, I believe that if a giraffe continually stretched it's neck out to reach for food, its body WOULD adjust by giving it a slightly longer neck. Maybe the difference would hardly be noticeable in one generation, but over the course of many generations as giraffes kept stretching their necks out for food, their necks would continue to grow. Not just for the mutated giraffes, but for MOST giraffes.
What do you think? Is evolution completely random, or might creatures have evolved to a point where their body is actually capable of adjusting/evolving to their surroundings?

evolution is an example of order in chaos. its as simple as that.

I dont think that applies to stick bugs.. you cant really make yourself look like a stick.
Evolution occurs very very very slowly. A bug would live on a tree. If it had offspring who did not blend into the tree, they would die. The offspring who blended in better, (ie those who were longer..) would live more, passing that trait on. Eventually the bugs that kept getting longer would be the ones survining, thus leaving us with present day stick bugs. Make sense?
I say life exists because it CAN exist. If the potential is there, it will eventually be realized. I think.

Remy, are you a Lamarkian:do you believe parents can pass acquired characteristics to they're offspring? It's a tempting idea, and it explains evolution, but does't explain how the DNA gets shuffled. In fact its so tempting if I could chose one, that would be it: mind and matter, teamwork. As for as I know though, noones shown how something like that would work.

I certainly agree that many evolutionary changes are completely random. But are ALL changes completely random? Is it possible that the giraffes that stretch their necks to reach the higher branches will grow longer necks as a result of their stretching?
Is it possible that stick bugs may have evolved as a result of actually trying to hide themselves behind a stick. Most animals have an instinct to hide from predators (which may have come from a purely random mutation that helped animals with this mutation to survive). So if a bug hides behind a stick enough, maybe it's body will evolve to help it do that better, just as the body evolves in the other examples I gave. Maybe bugs that hide behind a stick enough will actually move their body in such a way that it will eventually take a stick shape over the course of many. many generations? Isn't this a possibility?
