lungs, the result would be to reduce the size of the
area in contact with air, with the result that less
oxygen and carbon dioxide would be ex-
changed in the same amount of time and the
respiratory needs of the body would not
be satisfied. In other words, the individ-
ual values of air's density, viscosity and
pressure must all fall within certain
limits in order for it to be breathable
and those of the air we breathe do
exactly that.
Michael Denton comments on
this:
It is clear that if either the
viscosity or the density of
air were much greater, the
airway resistance would be
prohibitive and no conceiv-
able redesign of the respiratory
system would be capable of de-
livering sufficient oxygen to a
metabolically active air-
breathing organism... By plot-
ting all possible atmospheric
pressures against all possible oxy-
gen contents, it becomes clear that
there is only one unique tiny area...
where all the various conditions for
life are satisfied... It is surely of enor-
mous significance that several essential
conditions are satisfied in this one tiny re-
gion in the space of all possible atmos-
pheres. 63
