It is important to take note of how many conservatives on this thread either deny, or express skepticism about evolution....and then remember that next time they howl in protest when someone correctly writes that the GOP is an anti-science party.
Evolution is one of the most firmly established tenets in science, has been repeatedly tested by the scientific method, and has stood the test of time through multiple lines of evidence, including but not limited to the fossil record, DNA and genetics, anatomy, and even direct observation. Interesting questions remain, as they always do in science. But theory is so overwhelmingly supported by the preponderance of evidence, it has been elevated to one of the most basic scientific tenets there is, hands down.
