It suggests that the whole of nature is part of the divine self; it shows how the exploitation of nature impoverishes the very richness of divine experience; it encourages a respect for the intrinsic value of individual organisms; and, in saying that God loves the world as a self loves a body, it suggests that embodiedness itself is a good to be cherished rather than an evil to be avoided (McFague, 74).

Ecophysiological process - Individual organisms respond to environmental variability, such as climate change, through ecophysiological processes which operate continuously, generally at a microscopic or sub-organ scale.

That is, those events which are later than others lie in the same direction as the more evolved stages of the biosphere, the more developed stages of individual organisms, the more entropic states of closed physical systems, or the events of a causal chain which can be the effects but not the causes of a given event on the chain.
The use of the term «purpose» here does not warrant, by itself, McHenry's conclusion that an individual organism alters the environment to «its own purpose,» although the passage does not exclude the presence of purpose in individual organisms.

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?
RB: The goal of an individual organism is to maintain the form of the individual organism.
While it is evident to science that there is a functional «teleonomy» or machine - like purposiveness in individual organisms (for example, the fish's eye is constructed so as to enable it to see under water, the heart toward pumping blood, the human brain toward problem - solving, etc.), still there is no hard evidence that life itself, terrestrial evolution or the universe as a whole has any overarching meaning.
The most important problem, however, is that of conceptualizing «health» and «wholeness» as functions of the individual organism, when, and by contrast, the Christian tradition has tended to speak of the salvation - health linkage within a larger understanding of the destiny of the whole people of God.
