What is the fibonacci sequence in nature4/28/2024 ![]() To find out more visit our collection of articles about Fibonacci and his mathematics. The sequence is also closely related to a famous number called the golden ratio. Fibonacci and the original problem about rabbits where the series first appears, the family trees of cows and bees, the golden ratio and the Fibonacci series, the Fibonacci Spiral and sea shell shapes, branching plants, flower petal and seeds, leaves and petal arrangements, on pineapples and in apples, pine cones and leaf arrangements. You can find it, for example, in the turns of natural spirals, in plants, and in the family tree of bees. Fibonacci in Nature One of the beauties of the Fibonacci sequence is that the series is evident all over the natural world. Real rabbits don't breed as Fibonacci hypothesised, but his sequence still appears frequently in nature, as it seems to capture some aspect of growth. And from that we can see that after twelve months there will be pairs of rabbits. These shapes are called logarithmic spirals, and Nautilus shells are just one example. The sequence is also closely related to a famous number called the golden ratio. ![]() You can find it, for example, in the turns of natural spirals, in plants, and in the family tree of bees. Starting with one pair, the sequence we generate is exactly the sequence at the start of this article. Mathematicians have learned to use Fibonacci’s sequence to describe certain shapes that appear in nature. Real rabbits dont breed as Fibonacci hypothesised, but his sequence still appears frequently in nature, as it seems to capture some aspect of growth. Therefore, the total number of pairs of rabbits (adult+baby) in a particular month is the sum of the total pairs of rabbits in the previous two months: Writing for the number of baby pairs in the month, this gives etc, each number is the sum of the two numbers before it). Writing for the number of adult pairs in the month and for the total number of pairs in the month, this givesįibonacci also realised that the number of baby pairs in a given month is the number of adult pairs in the previous month. There is a special relationship between the Golden Ratio and Fibonacci Numbers (0, 1, 1, 2, 3, 5, 8, 13, 21. He realised that the number of adult pairs in a given month is the total number of rabbits (both adults and babies) in the previous month. Fibonacci asked how many rabbits a single pair can produce after a year with this highly unbelievable breeding process (rabbits never die, every month each adult pair produces a mixed pair of baby rabbits who mature the next month). Humans are hardwired to identify patterns, and when it comes to the Fibonacci numbers, we don’t limit ourselves to seeking and celebrating the sequence in nature.
