Someone posted in another forum that "Evolution is the result of hundreds of thousands of years of natural selection." Is that true?

How long approximatly did it take for the single celled organisms to change into something like say a fish. Probably quite some time I'm guessing.
Now, how long have humans been estimated to walk the earth? Also for quite some time.
To me evolution is more of a change from one species to another.
Are we a different species than that of early man?
Did natural selection make us the way we are?
And if we did in fact come from single celled organisms, why havn't we changed into some other type of creature completely?

Phobos said:Perhaps you meant 'why hasn't H. sapiens changed into something else yet?' It takes time. We are still evolving.

Yes that's what I meant. So what are some examples of our evolving? I know we have the brain thing going on and we're a little bit smaller but other than that I don't see much. I know it must take time but still. And I'm wondering about this too, why don't we see lower life forms, such as let's say apes, evolving into something more advanced? If we did it, shouldn't there be half man half apes walking around?

AMF8 said:Natural selection + Reproduction + Long periods of time = Evolution
Evolution is the gradual process by which living organisms change and diversify over time. It is driven by natural selection, which is the mechanism by which certain traits become more or less common in a population based on their ability to survive and reproduce.
Evolution is a slow process and can take millions of years to produce significant changes in a species. The exact amount of time varies depending on the species and the environmental conditions.
There is a wealth of evidence for evolution, including the fossil record, genetic similarities between different species, and observations of natural selection in action. Additionally, the principles of evolution have been repeatedly tested and confirmed through scientific experiments and observations.
Yes, evolution can be observed in real time through processes such as artificial selection, where humans intentionally breed plants or animals for certain traits, and natural selection, which can be observed in populations of organisms adapting to changing environments.
No, evolution is a scientific explanation for the diversity of life on Earth and does not address the existence or non-existence of a higher power. Many religious beliefs and interpretations are compatible with the concept of evolution.
