We must recognize that in this context «adaptation» is strictly defined in terms
of survival values and that, generally speaking, it is the simpler
forms of organization that possess the greatest staying power: living systems, no matter how fantastically intricate - and well organized they might be, have a much shorter span
of existence than, say, a rock crystal, or a
single stable
atom.34
«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.
