Apparently you don’t understand what a tautology is. The question of the particular mechanism for survival is beside the point. The point is that “fitness” is defined in terms of survival, and survival is explained in terms of “fitness.” That’s a tautology.
I’m not claiming that the theory of evolution is nothing but a tautology. I am merely saying that it can be cynically viewed as a tautology just as easily as ID can, if not more so. People in glass houses should avoid throwing stones.
ID is vacuous, if not tautological for the reasons I have given. Mainstream theory of evolution makes specific statements about how genomes change over time. ID makes no such statements. It says nothing about how or why genomes change over time.
Russ, would you mind explaining how ID can be disproven?
No, what you cited is circular reasoning. A tautology is a compound proposition’s truth value being unconditionally true regardless of the truth value of the propositions components.
