Coevolution of species in competition: A Theoretical Study. 

 -  Proceedings of the National Academy of Sciences of the United States of America, 78(2), p.1081-1084, 1981 .
<br/><br/> A model is presented for the coevolution of several species in competition, each species being genetically variable at one locus with respect to this competition. A function was found that is maximized during coevolution. This maximization principle was used in order to study the result of competition for a single resource on the utilization functions of the species competing for that resource. In particular, the conditions under which ecologicalcharacter displacement can evolve were examined.
