Birch and Cobb maintain that the ecological model is more adequate than the mechanical model for explaining DNA, the cell, other biological subject matter (as well as subatomic physics), because it holds that living things behave as they do only in interaction with other things which constitute their environment (LL 83) and because «the constituent elements of the structure at each level (of an organism) operate in patterns of interconnectedness which are not mechanical» (LL 83).

If, on the other hand, we define evolution in the Darwinian sense — as a process of random mutation and natural selection by which all living beings have arisen by chance from single - celled organisms over 100's of millions of years — we may not be on equally firm ground from a scientific perspective.
At the cellular level, cells are subjects and the multicellular organism to which they belong is also a subject.
Under Child's theory there is complete continuity from the reaction of the cell with its environment, which constitutes the primary metabolic gradient, and from the later reactions, by which the pattern of the developing embryo is laid down in accordance with the changing gradient pattern, to the intellectual processes by which the adult organism adjusts its relations to the outside world.
It may be thought of as a supermolecule composed principally of C, H, O, N, P and S.
