 Monod explains that the teleonomic performance is judged through natural selection and this system retains only a very small fraction of mutations that will perfect and enrich the teleonomic apparatus.Monod gives the example of antibody development to show how chance combinations can give a well defined solution.He states that the source of information for the antibodies associative structure is not the antigen itself but is instead the result of many random recombinations of part of the antibody gene.
