Fractal Biology

A fractal can be described as a pattern that contains itself on smaller and larger scales. One simple example of a fractal is a tree; it contains the same pattern in the trunk, branches, and leaves. Each time the tree branches it forms a new iteration of its fractal shape.<p>Systems form patterns which act as a components on a higher scale. When the type of interaction between components is the same on multiple scales, a fractal emerges.<p>Biological systems appear to have a fractal property, …
