Abstract
In my undergraduate course in biology at Caltech in the late 1950s, a cell was understood simply as a variety of chemical reactions going on inside a tiny test tube.1 Now, 50 years later, scientists know that the structure inside a cell is far more complex and exhibits elegant organization suggestive of a Designer.
