The Understanding Evolution for Teachers website makes the usual claim that evolution is a fact, but because that is undefendable it is first careful to redefine evolution.
Evolutionists face a dilemma. They cannot forfeit their dogma that evolution is a fact, but when confronted with even a Biology 101 student's questions the claim quickly is shown to be false. Of that there is absolutely no question.
Readers may wonder how I can know it is false. Is this not yet more dogma? The evolutionist spouts his dogma, and the skeptic retorts with his counter dogma. Isn't this the same old he said she said of the origins debate?
No, we need to be careful. I am not saying evolution is absolutely false, I am saying the claim it is a fact is absolutely false. Whether or not evolution (and in what flavor) occurred is a question of distant history. Whether or not evolution is a fact is a question of our current level of knowledge.
I try not to be dogmatic about ancient history, especially when dealing with underdetermined questions. But it is not dogmatic to point out that evolution is not a fact. In fact, it would be dishonest to say otherwise.
The consensus, indeed overwhelming, position within evolutionary thought is that evolution is a fact, or beyond a shadow of a doubt, or highly compelling, or ... well, pick your favorite superlative, it probably has been used by evolutionists.
But evolution is not a fact, and that is a fact, no question about it. Evolutionists attempts to support their claim are, frankly, downright silly. Evolution may be true, but it is not true that we know it is true--far from it.
And so increasingly evolutionists are resorting to whitewashing their claim. They cannot admit it is not a fact, so they quietly switch shells. Suddenly evolution is not the idea that the species have evolved one from another. It is no longer mutations and other happenstance mechanisms creating incredibly complex designs.
Instead, evolution is now merely change over time. Over eons of time life has changed, that's it, that's evolution these days. As the Understanding Evolution for Teachers website put it:
At the heart of evolutionary theory is the basic idea that life has existed for billions of years and has changed over time.
Overwhelming evidence supports this fact. Scientists continue to argue about details of evolution, but the question of whether life has a long history or not was answered in the affirmative at least two centuries ago.
Of course once the new convert is won, then the definition quickly reverts to what we all know evolution really to mean. Call it an equivocation, an obfuscation, or whatever, this is simply a dishonest whitewash. It is a debating trick that evolutionists are increasingly using to avoid their own absurdity.
The website is ostensibly a pedagogical tool, but in fact it is a lie.
