n the bodies of living things, there are a great many
inter-related mechanical designs: the detailed struc-
ture of tiny hairs that cause cells, invisible to the
naked eye, to clear the respiratory tract; the special
systems that allow fragile moths to survive in deadly
cold; and the power in its feet that allows the gecko lizard to climb
up sheer walls and even walk on ceilings.
Once again, chance could never bring such flawless structures
into being.
The structures, adapted to living things' environments, and the
intelligent behavior they exhibit show us the magnificent artistry of
God, Who knows all forms of creation.

THE HEATING SYSTEM IN WINTER MOTHS
Winters are harsh in Central Asia, Siberia and Northern Europe.
Lack of food and bitter cold cause the deaths of many living things.
Yet despite the appalling weather conditions, a few manage to sur-
vive. One of the most astonishing is, without doubt, a delicate moth.
The answer to how these fragile creatures manage to survive lies
in their bodies' perfect heating system.
