In science a "theory" is an idea that is supported by factual information with the hope that one day enough facts will be gathered to move a theory into the realm of being considered a scientific fact. Further down the line from Fact to Theory is Hypothesis.

But the theory of evolution finds it's major support not from facts but from hypothetical interpretations of evidence. Scientists take the fact that natural selection causes variations within a species and "hypothesize" that this could lead to one species becoming a totally different species.

Scientists take the fact that radiation causes mutations and "hypothesize" that random mutations added vast amounts of useful information to the DNA structures of the ancestors of every plant and animal alive today.

Given these truths, should the theory of evolution be reclassified as a hypothesis?

I know that frozen pig skin has been used to prevent scarring with burn victims, but today I read an article that two people have regrown fingertips by applying pig bladder extract powder to the surface. How can this be possible?

Charles Dawin threw in a few surprises when he took his intellectual journey 1831-36, and came back with a collossal bank of data, that even he found hard to digest.
By 1846 he had published papers that put him in the top rank of scientists.

Many of Dawins theories have been torn apart over the years, and then put back together again, however, we go on seaching for the truth. What next?
