SJL's link includes this near the end..

"DNA functions like a software program. We know from experience that software comes from programmers. We know generally that information-whether inscribed in hieroglyphics, written in a book or encoded in a radio signal-always arises from an intelligent source. So the discovery of information in the DNA molecule, provides strong grounds for inferring that intelligence played a role in the origin of DNA, even if we weren't there to observe the system coming into existence.

This is some combination of these informal fallacies. (and maybe several others implied). It gets you nodding "ok...sure" about certain seeming facts, then asks you to make a jump to 'obvious' conclusions.


Fallacy of Weak Analogy

Complex Question Fallacy

Cum Hoc Fallacy

Sweeping Generalisation Fallacy

Subjectivist Fallacy


It is NOT obvious that conceptually similar structural similarities demand similar causal assumptions.
