Nature forms around certain building blocks, the Fibonacci sequence being one of them. This beautiful video shows it quite clearly.
The Fibonacci sequence is a series of numbers. it starts with 0 and 1. By adding the most recent two numbers together you get the next result, so in the first instance you get 1. The sequence thus far is 0, 1, 1. By adding the last two number this time you get 2. 0, 1, 1, 2.... The sequence continues to be generated in this manner. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 etc.
However, while it is interesting that some biological specimens do conform to the Fibonacci numbers, not all patterns in biology do, it is not an underlying sequence that determines biological structures! It is simply an example of one of the patterns humans make of natural phenomena. This page in particular does a really good job of debunking that particular myth.
And for those seeking some peace and relaxation this Monday morning, here is another beautiful video from the same creators of the video above. Based on an Escher woodcarving and something I found to be quite relaxing earlier today.
Skeptical kinkster musing on whatever takes my fancy!
