tion splendidly even while the creature is still in the embryo
phase. To maintain that such a movement came about through
random mutations and functions in perfect manner in all ver-

The Heart Muscle Cells: the Only Ones
Moving Rhythmically in the Body

The body consists of some 100 trillion cells, each with
different functions and properties. Some, like the red
blood cells, possess no nucleus. Others, like those in
the windpipe, have minute hairs. Some have
