MODEL #1 NARRATIVE. “Suppose, for example, that a molecule carries out a particular catalytic function. If an association with another molecule enhances that function — for example, through structural stabilization — then natural selection can favor the association. The second molecule is initially beneficial although not essential. The second molecule may become essential, however, if an inactivating mutation in the first molecule is compensated for by the presence of the second.”
