The problem of the reduction of biology to physical chemistry has raised numerous controversies for several years. The reader is referred to Ayala & Dobzhansky (1974), Hull (1972, 1973, 1974, 1976), Polanyi (1967, 1968), Roll-Hansen (1969, 1974), Ruse (1971, 1976), and Schaffner (1967, 1969, 1974, 1976). Supporters and opponents of reduction are continually exchanging arguments and it is almost impossible, even for an objective reader, to discern who is correct.
The partisans of reduction insist that physical chemistry, contributes a very useful explanatory schema for the understanding of a certain number of biological processes. For instance, in genetics, great progress has been realized because of the contribution made by chemistry in the determination of the genetic code and in the understanding of the molecular mechanisms governing the laws of heredity.
