The Fact of Cre a tion 221

a human ventured to do something like that, he would probably undergo a
brain shock followed by a brain haemorrhage. A woodpecker, however, can
peck a hard tree trunk 38-43 times between 2.10 and 2.69 seconds and noth-
ing happens to it.
Nothing happens because the head structure of woodpeckers are cre-
ated as fit for this job. The woodpecker's skull has a "suspension" system that
reduces and absorbs the force of the strokes. There are special softening tis-
sues between the bones in its skull. 189

The Sonar System of Bats
Bats fly in pitch dark without trouble and they have a very interesting
navigation system to do this. It is what we call "sonar" system, a system
whereby the shapes of the surrounding objects are determined according to
the echo of the sound waves.
A young person can barely detect a sound with a frequency of 20,000
vibrations per second. A bat furnished with a specially created "sonar sys-
tem", however, makes use of sounds having a frequency of between 50,000
and 200,000 vibrations per second. It sends these sounds in all directions 20
or 30 times each second. The echo of the sound is so powerful that the bat
not only understands the existence of objects in its path, but also detects the
location of its swift-flying prey. 190

Whales
Mammals regularly need to
breathe and for this reason water
is not a very convenient environ-
ment for them. In a whale, which is a
sea mammal, however, this problem is
handled with a breathing system far
more efficient than that of many
land-dwelling animals. Whales
breathe out one at a time discharging
90% of the air they use. Thus, they
need to breathe only at very long inter-
vals. At the same time, they have a
highly concentrated substance called
