Is evolution exclusive only to earth?

Question

If evolution always was, then what proof is it that evolution has occured elsewhere. If not why doesn't evolution apply through out the universe?

Goring, are you even allowed to mention a creator in the science and mathematics section?

Ahh, I liked Goring answer. Anyway, I won't pick a best pick for this question, I'll let you all decide.

Answer 1

The nice thing about science is the rules are universal, testable and repeatable. A chemical reaction on Earth will happen the same way under the same circumstances on Titan. If life exists elsewhere, evolution will work the same way in their environment as it does here on Earth.

Answer 2

Evolution requires only two ingredients:

1) Imperfect procreation

and

2) Selection.

Imperfect procreation you get by definition from life. If something does not replicate itself, we usually don't call it life.

That it will be imperfect is pretty much a given once you apply thermodynamics to something.

And selection is an unavoidable feature of the physical world: if you live you can get killed. How likely it is that you get killed depends on how well you are adapted.

So if there is life out there it will, indeed evolve.

If you want, this line of reasoning is as close to a mathematical proof as one can get in the real world in which mathematical proofs do not exist.

If I had to pick one thing that I absolutely know about life on other planets, it would be the certainty that it evolves. Nothing else makes sense. That is not to say that foreign life can not be dominated by processes other than evolution. What it simply means is that evolution will be present on top of anything else that might be driving that other form of life.

Answer 3

There is no proof it has occurred only on Earth. But there is no proof it hasn't. Sience assumes the same natural laws apply everywhere in the universe until it can be proved otherwise, so it assumes the same kind of evolution could and would take place anywhere in the universe.

Answer 4

yes, that is exactly right - it could happen anywhere. That is why there is so much research, both on earth and in the rest or the universe, for the conditions that caused the first molecules that led to life as we know ti to occur.

It is reasonable that it would happen in an environment that was like earth in physical terms, but it may also be possible that the way the chemistry happened here may not be the only way it could have happened. Although I think the consensus is that it is most likely to have happened pretty much the way it happened here.

Answer 5

We don't know if life exists elsewhere, but if it does, it will evolve. We have no reason to doubt that natural laws apply everywhere in the Universe the same way.

Answer 6

We have not yet found any life on other planets. When and if we do, we shall surely find evidence of evolution there. Laws of science are universal.

Answer 7

Evolution is a principle that will follow in any place that has the following conditions:

Life
Variability in sexual genetics which leads to variable phenotypes
An Environment (any kind)
Selective advantage of phenotypes in an environment.

Answer 8

Since we haven't actually found any life anywhere else, there's nothing on which to base any such statement about evolution's ubiquitousness or limitations. We are still exploring our own solar system, and we are not capable yet of exploring others, so evolution could be going on in any of a trillion places right now and we can't tell.

Answer 9

First of all, before even starting to think of an answer, to even think of this question, why separate earth and the universe? On this kind of subject, it is imperative to take a broader approach of things, and avoid the typical self-centered, geocentric point of view humanity has had for a long time.
Are we speaking of the evolution of life, of planets, stars, systems?
Are we, as a human race, mature enough to grasp the meaning of all of this?


Sorry for answering your question with questions!

Answer 10

It was our Creator that from the creation of the substance of space all mass strucures evolved form it. The evolution velocity relative to the time on earth was Exremely rapid. And our Creator evolved man out of the atoms of the clay at even a faster velocity.
Therefore because of synergys The whole creation porcess of the Universe had to be in very rapid sequencial periods. Otherwise the bees could not live without the flowers and the birds could not live without the flies it the Creation time was not in terms of 24 hours day period.
