The second question has in fact two facets: (a) how does it arise in the development of the individual organism during the process of growth from the moment of fertilization of the egg; and (b) how does the egg itself come to get that way — that is to say, how can we conceive of evolution as having «designed» the cell?

We see Nature combining molecules and cells in the living body to construct separate individuals, and the same Nature, stubbornly pursuing the same course but on a higher level, combining individuals in social organisms to obtain a higher order of psychic results.

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).
