After having read this book you will never see birds in the same way again.

The unexpected patterns displayed by a bird's body have been seen as bizarre events that demanded little attention or were described as 'amazing curiosities'.

None of these surprising features seem to be fortuitous. They appear to be an integral part of a rigid order and a coherent geometry, which is directed by simple gene interactions and molecular cascades occurring at various cellular levels, and at different times, during the organism's development.

A novel geometry unfolds in front of your...

New concepts arise in science when apparently unrelated fields of knowledge are put together in a coherent way. The recent results in molecular biology allow to explain the emergence of body patterns in animals that before could not be understood by zoologists.

There are no "fancy curiosities" in nature. Every pattern is a product of a molecular cascade originating in genes and a living organism arises from the collaboration of these genes with the outer physical environment.

Tropical fishes are as startling in their colors and geometric circles as peacocks. Tortoises are...
