The beauty of nature may not seem to be ordered by mathematics.

But an intriguing series of numbers exist which explain patterns of growth throughout the natural world, and was identified with the help of rabbits.

**Leonardo Fibonacci1202 AD**

At the beginning of the 13th century, Italian mathematician Leonardo Fibonacci was studying the growth of rabbit populations.

He created an idealized scenario.

A newly born pair of rabbits occupy a field. At the end of the first month, they mate.

When the second month ends, the female produces a new pair.

Three months on, the original female produces another pair.

After four, the original female produces another new pair, and the female born two months ago produces her first pair.

And so on.

Fibonacci had discovered a sequence describing growth in nature.

**Sequence:An ordered set of mathematical objects**

In Fibonacci's sequence, each term is created by adding the previous two terms together.

Numbers from Fibonacci's sequence occur time and time again in nature, wherever there is growth.

From the number of petals on a flower to the superstructure of trees.

Visualized as a sequence of squares, each the width of the previous two added together, Fibonacci's sequence is instantly recognizable.

Within this, a perfect spiral can be traced.

Another familiar pattern, that occurs naturally.

The Fibonacci sequence is just one example of how maths helps us organise and understand the natural world.
