So which came first? In his magnum opus, Signature in the Cell, Dr. Meyer puts on the table what went through my mind when I took my first biochemistry class: How did this closed loop get started? Whatever made the loop could not have made the first DNA molecule the same way that it is made now. And the DNA and protein interaction is just one of many closed loops in perhaps the most efficient factory ever observed—the cell.

In 500 pages, Meyer takes his readers on a journey from working as a geologist in Texas, to walking the halls of Cambridge studying the philosophy of science, to being interviewed on television for his theories on origins. The value of his book is not merely in its conclusion that intelligence best explains the source of the DNA code; it is in the process Meyer uses to bring us to this conclusion. The reader sees the scientific process firsthand.
