Here is the Language of Evolution
But this is hardly a scientific hypothesis. In science hypotheses and theories are constructed and predictions are made based on the hypothesis. If the prediction is successful then the hypothesis escapes falsification. If not, then the hypothesis fails. It must be modified or perhaps even discarded.
This reasoning process is sometimes denoted as IF P, THEN Q. And if NOT Q, THEN NOT P.
In other words, if hypothesis P is true, then prediction Q will also be true. And if Q is found to be false, then P is false.
This is the language of science. Of course there are other ways of doing science as well, but the evolutionary claim that “Evolution and only evolution predicts certain things in biology” is, on the other hand, very different. It is not the language of science but rather the language of metaphysics. For science cannot know that a hypothesis, and only that one particular hypothesis, can explain something we observe.
This reasoning process is denoted as IF AND ONLY IF P, THEN Q.
In other words, if hypothesis P is true, and only if hypothesis P is true, then Q will also be true.
In this case Q is not a prediction, but rather something that has already been observed. Q is already known to be true. And P is the theory of evolution. The claim is that there are no possible explanations for these aspects of biology, except for evolution.
Straightaway one can see this claim entails knowledge of all possible explanations. Science has no such knowledge.
What this claim reveals is evolution’s underlying religion foundation that derives from the Enlightenment and remains as crucial as ever today. This claim, in its many different versions, pervades the evolutionary literature. It is the language of evolution.
