Optimal branching of vascular vessels minimizes work: mammals
Vascular and respiratory vessels in mammals minimize the amount of biological work required to operate by being arranged hierarchically.

"The branching structures found in mammalian cardiovascular and respiratory systems have evolved, through natural selection, to an optimum arrangement that minimizes the amount of biological work required to operate and maintain the system. The relationship between the diameter of the parent vessel and the optimum diameters of the daughter vessels was first derived by Murray (1926) using the principle of minimum work. This relationship is now known as Murray’s law and states that the cube of the diameter of a parent vessel equals the sum of the cubes of the diameters of the daughter vessels." (Barber and Emerson 2008: 180)
[This mathematical structure is also found in trees and other organisms that exhibit branching]
