ABSTRACT

On any close examination the whole notion collapses in inconsistencies. The growth of an organism follows a fixed developmental programme, which has a certain latitude or flexibility in response to environmental circumstances, to be sure, but for which the essential ‘design’ is carried from the beginning in the inherited genetic material. This ‘design’ of course has been produced over many generations, through evolution. If we wanted an

analogy for the development of the organism in the design or architectural world, it would be much more reasonable to compare it to the process whereby a finished design – let us say, expressed in a set of drawings or in instructions of some other type – is realised in material form, through those instructions being carried into effect by the fabricator or the builder.
