Biomimetics: Technology Imitates Nature

Some of the towers that prairie dogs build are taller than others. Their dif-
ferences in height give rise to different levels of air pressure in the tunnel
entrances. This way, air enters towers with low air pressure above them
and emerges through ones with high pressure. Air drawn into the tunnels
passes through all the nests, thus establishing an ideal air circulation sys-
tem. 133
To construct a ventilation system such as employed in prairie dogs'
tunnels, knowledge of tunnel building, of high and low air pressure, and
how they change with altitude are all essential. All these considerations
require consciousness, and all these activities indicate the presence of rea-
son and judgment. Therefore, we need to examine the source of this intel-
ligence in the prairie dogs, since clearly it does not belong to the animals
themselves—and, contrary to what evolutionists claim, cannot have re-
sulted from blind chance.
