Fractal Structure Of Bone
Recently scientists have discovered that the fractal structure of bone extends down to the nanoscale.
Here is a link to the article in Science: http://science.sciencemag.org/content/360/6388/eaao2189 .
Commentary at ScienceDaily: https://www.sciencedaily.com/releases/2018/05/180503142827.htm , includes the following comment.
“Fractals are common in Nature: you can see self-similar patterns in lightning bolts, coast lines, tree branches, clouds and snowflakes. This means that the structure of bone follows a fundamental order principle in Nature.
The authors believe that the fractal-like structure of bone is one of the key reasons for its remarkable attributes.”
Self-similar structure rules in nature; as above, so below.
