the proof that even nature refuses to make the same mistake twice

means The unique pattern of ridges on the tip of a finger, or by extension any distinctive mark that identifies one person or thing from all others.

from A plain compound of "finger" and "print" — both old, sturdy English words. "Finger" traces back to Old English fingor, with cousins across the Germanic languages, while "print" came through Old French preinte, "an impression," from Latin premere, "to press." So the word is literally "the press-mark of a finger." Though humans surely noticed these whorls for ages, the term gained its modern weight in the 19th century, when it became clear the ridges were unique to each person and could pin a name to a crime.
