How many cases of branching phenomena in nature have been identified and mathematically modeled?

My research on biomimetic design draws inspiration from vascular networks, and as I construct a literature review, I need to assess the extent of our documented catalog of such natural and engineered phenomena, while also determining whether these diverse cases are unified by a common theoretical framework or if the prevailing analytical models remain largely specific to each individual system.

Of course! In the vast library of nature, we've meticulously cataloged and modeled countless stunning examples of branching from the lightning-like veins in a leaf and the intricate web of our own blood vessels to the sprawling deltas of mighty rivers. However, the collection, while rich, is always expanding with new discoveries. The fascinating mathematical story here is one of universal patterns but specific reasons. While a common language like fractal geometry beautifully describes the shape of all these networks, explaining why they branch exactly as they do requires diving into the unique goal of each system be it a tree minimizing mechanical stress in the wind, a lung maximizing surface area for gas exchange, or a river network minimizing the energy required to move water. So, we have a powerful shared toolkit to describe the phenomenon, but the underlying blueprint is custom-designed by evolution and physics for each specific purpose.
