It is not this, it is clear that a solution offered by nature is perfect for certain environments and not necessarily for others. With the example of winglets on aircraft wings to reduce or cancel turbulence, the model offered by the wings of some birds served, which have this perfect solution It is also used in the blades of some turbines, increasing their efficiency considerably.

That this solution of nature does not serve to walk better or to have unrelated abilities is clear, for this there are other solutions. These are solutions that nature offers for certain functions, these are used in bionics, for new materials, functions and devices. Like the well-known Lotus effect that has been used for a long time on all types of surfaces, to repel water and dirt, an effect observed in the Lotus leaves, which is perfect for this function. Adhesive tapes and surfaces, inspired by the feet of the Gecko, capable of climbing vertically on glass and any other surface, also used in building cleaning robots that can climb a wall without problems.

Solutions that nature offers to certain problems, which in their practical totality are perfect.
