A couple months ago I got curious about the spiral pattern of seeds on a sunflower, and my sister-in-law Bethany told me it was a Fibonacci pattern. So I looked up what makes up this pattern, and I started to notice it everywhere in nature:
These spirals are simply built on the golden ratio, 1:1.6180339, which is expressed with the letter φ. Basically, you get it by having each consecutive new growth (leaf, seed, etc) start moving outwards at an angle of 222.49°, which is 360°/ 1.618. Plants follow this pattern because biologically, it is the most efficient form of growth, and theologically, because God loves beauty. The number of spirals in either direction will always be one of the fibonacci sequence numbers.
