![]() ![]() As random as nature may appear at times, occasionally there is an underlying order. Most flowers, for example, will have a number of petals which correspond with. If you place squares next to one another in which each new square has the width of the next number in the Fibonacci sequence, the resulting formation is a spiral that appears exactly in the nautilus - and in the spiral of hurricanes. For starters, Fibonacci numbers can be found in the natural world all around us. The petals unfold more and more and the sequence increases. ![]() I like it because the petals arent spread out and the spiral is more obvious and clear, like with the shell. Perhaps the most famous example of all is the Fibonacci sequence expressed in the nautilus shell. For example, the Fibonacci sequence has been used to describe the patterns of reproduction in populations of rabbits and bees. Flowers of all kinds follow the pattern, but roses are my favorite kind to use as an example of the Fibonacci Sequence. Artists recognised that the Fibonacci Spiral is an expression of an aesthetically pleasing principle the Rule of Thirds. Using the blank graph paper on the next page, replicate the example piece of Fibonaccis. Mathematicians found that it was abundant in nature, in places as diverse as the proportions of the human face, the flowering of an artichoke, and the ancestry of the ideal bee. For example, the distance between the tips of a starfish’s arms compared to distance from tip to tip across the entire body is very close to the golden ratio, and the eye, fins and tail of dolphins all fall at points along the dolphin’s body that correspond to the ratio. Where do we find the Fibonacci Sequence in nature 3. In this lesson, students will explore examples of the Fibonacci Sequence in nature and reflect on what this mysterious code reveals to us about our loving Creator. Yet, the golden ratio is far more common among all living creatures, including those in the sea. The grandest feats of engineering and construction, and often the most beautiful, reflect the proportions of the Fibonacci Sequence. So where do these show up in the ocean? For one, the Fibonacci numbers themselves are common: Sea stars and sand dollars, for example, have five points, while squids and octopuses have eight arms. As the series increases, the ratio of any two consecutive Fibonacci numbers becomes increasingly closer to the “golden ratio,” which is approximately 1.618. Though the numbers look random at first - 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55… - they actually follow a simple pattern: the next term in the series is the sum of the previous two terms. ![]() Credits: Raiana Tomazini-Wikipedia, Wikipedia, NASA Additionally, we hope it helps you become more aware of how everything is connected, infinite and eternal.A Fibonacci spiral, a nautilus shell cut in half, and a hurricane all share links to Fibonacci numbers. Visit BYJU’S to learn Fibonacci numbers, definitions, formulas and examples. We hope it inspires you to notice it more in your own life. Fibonacci sequence is defined as the sequence of numbers and each number is equal to the sum of two previous numbers. We have compiled a slideshow showcasing the many, many occurrences of the Fibonacci Sequence in nature. Examples of the Fibonacci Sequence in Nature The Fibonacci Sequence represents infinity and infinity represents what is eternal. The iteration continues infinitely, both ways. For example, the golden spiral is formed by plotting a quarter circle inside each of the squares. The round cell in the centre has a diameter of 20 microns. The DNA is shown in red, and the cell membrane is shown in cyan. The golden ratio is the ratio between the numbers (1.6). This composite confocal micrograph uses time-lapse microscopy to show a cancer cell (HeLa) undergoing cell division (mitosis). Similarly, each next number is found by adding the two numbers before it. ![]()
