«What we have described as globalization is remarkably close to Teilhard de Chardin's planetization, in which «[mankind, born on this planet and spread over its entire surface, come [s] gradually to form round its earthly matrix, a single, major, organic unity, enclosed upon itself.4 Thus the globalization of humankind could lead to the formation of a new kind of
living entity — a social
organism — on the same cosmic principle as that by which atoms join to form molecules, molecules join to form mega-molecules, mega-molecules unite to form
living cells, and innumerable
cells constitute an
organism.
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).

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 -

They owe their flimsy and precarious «existence» to the combinations of atoms, molecules and

The fact that
cells degenerate, that
organisms decay, that our own
lives ebb toward death, that civilizations eventually fall and that noble deeds and ideals fade into oblivion — all this makes us wonder how the universe could conceivably have any abiding seal of purpose.
And let's remember that evolution, while it's a theory, is a theory about the beginning and the transformation of
life based on things we have observed, namely that
cells change and mutate and that those mutations can produce
cells that are unique and new, and that it would follow that it's possible for molecules to form into single -
celled organisms which mutate and combine into multi-cellular
organisms which mutate, adapt, and grow over time into new forms of
life.
The Theory of Evolution only talks about how
life evolved from the first single
celled organism up till what we have today.

organisms with very few capabilities.
To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in
living organisms (e.g., cellular respiration, creating a charge across a membrane in mitochondria and nerve
cells) where the reactions are more complex and difficult to observe.
Starts with the first single -
cell organisms and end with modern
life forms.
The fields within biology are further divided based on the scale at which
organisms are studied and the methods used to study them: biochemistry examines the fundamental chemistry of
life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all
life, the
cell; physiology examines the physical and chemical functions of the tissues and organ systems of an
organism; and ecology examines how various
organisms interrelate.
