The Evolutionary Significance of Biological Templates

  • George Ledyard Stebbins


In his exciting autobiography, The Double Helix, James Watson cites an old but vague hypothesis about the nature of heredity as follows (p. 127): “The argument went that gene duplication required the formation of a complementary (negative) image where shape was related to the original (positive) surface like a lock to a key. The complementary negative image would then function as the mold (template) for the synthesis of a new positive image.” The remainder of his book tells the story of how he demonstrated that the gene is, in fact, a pair of templates which duplicates its pattern by making a new negative complementary to the existing positive simultaneously with a new positive complementary to the existing negative. The template principle is, therefore, the basis for the transmission of information in biological heredity.
