The Logical Fallacy of Unsubstantiated Inference occurs when a premise is given but cannot be shown to be true. This is the same or very close to a hysteron proteron. An inference is a conclusion. Every premise is supposed to be a conclusion of its own logical reasoning. It must be true or the logic is not sound. To be true, it must not be dependent on axioms, assumptions, stories, the opinion of experts, or any other fallacious problem. If it is not true, then the entire argument is not sound. An unsubstantiated inference is a premise that cannot be shown to be true.
Sandra: "We have observed information being added to the genome. This information is what is needed to drive molecules to man evolution. Therefore, we know that evolution is a fact."
Roxanne: "What makes you think that new information has been created and added to the genome, I mean information of the type that would be needed if there were to be such a thing as molecules to man evolution?"
Sandra: "Viruses add new information all the time. That is how evolution happened."
Roxanne: "Actually, your premise is based on an unsubstantiated inference. The addition of new information would be needed. Viruses merely move existing information around."
Sandra: "Well, mutations add new information all the time. That is how evolution happened."
Roxanne: "Mutations do create information, depending on how you define information. This information cannot account for molecules-to-man evolution since none of the common modes of mutation such as random letter changes, inversions, deletions, and so forth, have the ability to do what evolution requires. As complex as DNA is, thinking that this is about DNA is oversimplifying the situation. However, with the mutation story, you would only prove that molecules to man story is possible, but you have not begun to prove that it actually happened. So, you again have an unsubstantiated inference when you claim that this is how evoluton happend. Your premise, even if it were true, would not show that evolution happened. I know, by Divine revelation, that God created the Heavens and the Earth in six days and that living things produce after their kinds--not species. Scientifically, I know that there is great ability for variation within kinds of living things."
