The Rabbits problem is not very realistic, is it? There are many other interesting mathematical properties of this tree that are explored in later pagesat this site.Ġ, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987.

There are a Fibonacci number of rabbits in total from the top down to any single generation.

There are a Fibonacci number of new rabbits in each generation, marked with a dot.

The rabbits labelled with a Fibonacci number are the children of the original rabbit (0) at the top of the tree.

Thus 5, 6 and 7 are the children of 0, 1 and 2 respectively.

The rabbits have been uniquely numbered so that in the same generation the new rabbits are numbered in the order of their parent's number.

All the rabbits born in the same month are of the same generation and are on the same level in the tree.

Rabbits have been numbered to enablecomparisons and to count them, as follows: Now can you see why this is the answer to ourRabbits problem? If not, here's why.Īnother view of the Rabbit's Family Tree:īoth diagrams above represent the same information. The first 300 Fibonaccinumbers are here and some questions for you to answer.

Ĭan you see how the series is formed and how it continues? If not,look at the answer! The number of pairs of rabbits in the field at the start of each month is 1, 1, 2, 3, 5, 8, 13, 21, 34. At the end of the fourth month, the original female has produced yet another new pair, the female born two months ago produces her first pair also, making 5 pairs.

At the end of the third month, the original female produces a second pair, making 3 pairs in all in the field.At the end of the second month the female produces a new pair, so now there are 2 pairs of rabbits in the field.At the end of the first month, they mate, but there is still one only 1 pair.How many pairs will there be in one year? Suppose that our rabbits never die and thatthe female always produces one new pair (one male,one female) every month from the second month on. Rabbits are able to mate at the age of one month so thatat the end of its second month a female can produce another pair ofrabbits. Suppose a newly-born pair of rabbits, one male, one female, areput in a field. Fibonacci's RabbitsThe original problem that Fibonacci investigated (in the year1202) was about how fast rabbits could breed in ideal circumstances. This introduces you to the Fibonacci Numberseries and the simple definition of the whole never-ending series. Rabbits, Cows and Bees Family TreesLet's look first at the Rabbit Puzzle that Fibonacci wrote about and then at twoadaptations of it to make it more realistic. It can’t be told if galaxies follow a perfect spiral, because we can’t measure a galaxy accurately, but on paper, we can measure it and see the size.Contents of this page The icon means there is a You do the maths. The golden spiral can be found in the shape of the “arms” of galaxies if you look closely. Of the most visible Fibonacci sequence in plants, lilies, which have three petals, and buttercups, with their five petals, are some of the most easily recognised. The petals of a flower grow in a manner consistent with the Fibonacci.

This proportional growth occurs because the nautilus grows at a constant rate throughout its life until reaching its full size. Each new chamber is equal to the size of the two camerae before it, which creates the logarithmic spiral. When cut open, nautilus shells form a logarithmic spiral, composed of chambered sections called camerae. But is a hurricane actually a Fibonacci spiral? > Xah Lee Seashells

This pattern is much like the Golden Ratio. Your eye of the storm is like the 0 or 1 in the Fibonacci sequence, as you go on in the counter-clockwise spiral you find it increasing at a consistent pattern.
