## Overview

1, 1, 2, 3, 5, 8, 13, 21, 34. . . Look carefully. Do you see the pattern? Each number above is the sum of the two numbers before it. Though most of us are unfamiliar with it, this numerical series, called the Fibonacci sequence, is part of a code that can be found everywhere in nature. Count the petals on a flower or the peas in a peapod. The numbers are all part of the Fibonacci sequence. In Wild Fibonacci, readers will discover this mysterious code in a special shape called an equiangular spiral. Why so special? It mysteriously appears in the natural world: a sundial shell curves to fit the spiral. So does a parrot's beak. . . a hawk's talon. . . a ram's horn. . . even our own human teeth! Joy Hulme provides a clear and accessible introduction to the Fibonacci sequence and its presence in the animal world.

In the Fibonacci sequence each new number comes from adding up the two before and figuring the sum.

This number set is used to plot a graceful curving line that's often found in nature as part of its design.

Fibonacci creatures have a certain body part which fits the winding, coiling shape that spirals on this chart.

These parts are most important the help the beasts survice.
Finding food and fighting foes can keep each one alive.
