It is advocated that the H ‐bond patterns of the standard C – G and A – T base pairs have an evolutionary advantage over any other H ‐bond scheme accommodated within the Watson–Crick‐type geometry. A suggested proof of the statement is given by the Longuet–Higgins' sign‐reversing loop argument. The present analysis indicates a close relation with self‐organizational principles. © 1993 John Wiley & Sons, Inc.
