Naturally it is known, once the result has been verified and the distances/time/energy expenditure required have been measured. The evolutionary process admits no other than the most efficient solution, either by path or energy, especially in very old current species, all of them adapted to the maximum to their corresponding environment. Other solutions that nature offers even today are not yet well understood, such as photosynthesis, which only now with quantum physics is beginning to reveal how it works. Ceramic materials, harder than porcelain, created at room temperature in certain sea slug shells, spider silk that also cannot be reproduced satisfactorily… We are very advanced technologically, but it is a mistake to think that we are at the top of what we understand. There are still many unknowns, many, and until now we only understand part of 5% of what surrounds us and what we can reproduce. No more.
