Nothing other than entirely abstract things, like mathematics or philosophy can be proven to be true. In the real world, you only have theories that you can try and disprove.
Nothing is. A fact - to humans who live in a world of uncertainty - is so until proven otherwise. Considering evolution has yet to be disproven - it is fact.
The common definition of "fact"; "a thing that is known or proved to be true" - Evolution is proven and known to be true. If we're being pragmatic, not a lot of things are facts. However, I think we can say with enough certainty, evolution is a fact, without being too pragmatic.
In it's most basic form, evolution is nothing more than the proven theory that things change over time. You can argue the specifics, but the actual "big picture" theory is as sound as can be.
This does nothing to invalidate the theory or prove it to be untrue. There is plenty of proof and nothing that disproves it, ergo it is as useful to us as any fact would be.
it is the most evidence-supported theory currently in existence.
Yes, it is a theory, just like gravity, and I don't see you jumping out of windows.
"Fact" is defined as "a thing that is indisputably the case." (per google). Dispute exists - so Evolution is a theory, as is everything produced by science. In science, we refine theory as new evidence arises. Evolution is not a "fact" - but it is, indeed, the best explanation for what we see today.
Part of the argument we are having here is to determine if there are still legitimate disputes to be had, if not, evolution becomes closer to be coming a "fact". As well, pieces of a theory such as evolution can be disputable, while still remaining a "fact" as a whole. brianbreniser
A fact is "something that actually exists; reality; truth", and evolution is "change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift."
Since that type of change in the gene pool actually exists, evolution is fact.
There exists proof of evolution.
Evolution has been witnessed in the laboratory.
The very nature of scientific facts is that they are always changeable based on new evidence.
