Many believe in 'emergent' phenomena where if you put enough components together, put them in the right environment, and stress them properly they will react in unexpected and coherent ways that while describable and maybe useful from an external perspective can't fully be analyzed because the interrelationships are too complex. People were building bridges before they knew why the atoms in a beam of wood stuck together -- it probably wasn't even a matter they contemplated. They built complex bridgess before knowing fully how to analyze tensions and torques in such a structure. Likewise people will probably build useful biological wetware components and assemblies before knowing fully how they work.
