Art Selection, or the Preservation of Artworks in the Struggle for Art

The argument of George C. Williams's book Adaptation and Natural Selection is against what biologists call the group selectionist view — that individuals will act on behalf of their species, or at least on behalf of the group to which they belong.¹ Williams showed, and now most biologists agree, "no creature could ever evolve the ability to help its species at the expense of itself. Only when the two interests coincided would it act selflessly."² According to Matt Ridley, Williams is one of the towering figures in contemporary biology. Williams helps us to understand better what natural selection is and consequently helps us to understand better our place in the world. Williams claims that when we are dealing with life, "we are forced to invoke natural selection to achieve a complete explanation of an observed system."³ Physics and chemistry alone are not sufficient to explain life. Williams gives the example of a falling apple. If one has to explain the trajectory of the apple, the principles of mechanics are sufficient for providing an adequate explanation of the phenomenon.

If, however, we were asked how the apple acquired its various properties, and why it has these properties instead of others, we would need the theory of natural selection, at least by implication. Only thus could we explain why the apple has a waterproof wax on the outside ...why it contains dormant embryos....We would find that an impressive list of structural details and processes of the apple can be understood as elements of a design for an efficient role in the propagation of the tree from which it came."⁴

Of course, a little over a hundred years before Williams published his book, Charles Darwin published Origin of Species, in which natural selection is the linchpin of his theory of evolution. Natural selection for Darwin not only helped to explain the competitive climate of the living world but its luscious fecundity as well. Natural selection works like this: Let's say you have a population of large beaked and small beaked birds. The environment in which the birds live provides them with an abundant and nutritious supply of both large and small seeds. Typically the small beaked birds eat the small seeds. The large beaked birds are capable of eating both small and large seeds. However, a blight occurs killing off all the small seed producing trees causing the food supply of the small beaked birds to diminish to virtually nil. Given that the small beaked birds are unable to feed on the continued supply of large seeds, they are selected out or eliminated from that environment: either they must seek out another environment, or they die. The large beaked birds, however, are in this case more adaptable to the environment because they can eat large seeds, survive, and pass on their largebeaked traits to the next generation. Darwin characterizes this process as "the struggle for life." He says:

Owing to this struggle, variations, however slight and from what ever cause proceeding, if they be in any way profitable to the individuals of a species, in their infinitely complex relation to other organic beings and to their physical conditions of life, will tend to the preservation of such individuals, and will generally be inherited by the offspring. The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive. I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection, in order to mark its relation to man's power of selection. But the expression often used by Mr. Herbert Spencer of the Survival of the Fittest is more accurate, and is sometimes equally convenient.⁵

Darwin sums up his discussion of natural selection by saying that the idea explains...
