I've made my position on this crap clear before, but whenever I come across an article like this one, I can't help but reiterate, once again, that religion is not science.
It literally makes me a little sick to my stomach to think that people are making progress at getting the idea that evolution is unproven out there and into the science classes of our children.
Let's be perfectly clear about this: Evolution is a fact. It is only a theory in the sense that everything known to science is strictly speaking, "only" a theory. There is no absolute truth in science, but there are many scientific truths. That is, there are many "facts" about the natural world that it would simply be absurd to deny.
When you drop a brick on Earth, it will fall to the ground. You can rely on that. It's possible, however, that one day you'll drop a brick and it will just hover there. The chances are incredibly slim, but it is possible. This, of course, does not call the fact of the existence of gravity into question is any relevant way.
The same is true of evolution. While there is plenty to debate about the mechanism by which evolution takes place, there is no debate over whether or not organisms evolve. They do. That's it. They do. We've seen it.
Evolution is a fact and a theory. The two are not mutually exclusive.
Moreover, "fact" doesn't mean "absolute certainty"; there ain't no such animal in an exciting and complex world. The final proofs of logic and mathematics flow deductively from stated premises and achieve certainty only because they are not about the empirical world. Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us falsely for a style of argument that they themselves favor). In science "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional consent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.
Evolutionists have been very clear about this distinction of fact and theory from the very beginning, if only because we have always acknowledged how far we are from completely understanding the mechanisms (theory) by which evolution (fact) occurred. Darwin continually emphasized the difference between his two great and separate accomplishments: establishing the fact of evolution, and proposing a theory--natural selection--to explain the mechanism of evolution.
Or this...
So enormous, ramifying, and consistent has the evidence for evolution become that if anyone could now disprove it, I should have my conception of the orderliness of the universe so shaken as to lead me to doubt even my own existence. If you like, then, I will grant you that in an absolute sense evolution is not a fact, or rather, that it is no more a fact than that you are hearing or reading these words.
Compare these reasoned arguments with the argument of Southern Baptist minister Terry Fox of Kansas...
So here's the choice we face right now: Do we want our children to be taught the basic natural science that has been tested and proven by generations of natural scientists using rigorous scientific methods, or do we want them to learn ideas that have met the truth standard of "what most people in Kansas think"?
