Abstract: A method for developing an evolved structure by artificial evolution includes: obtaining one or more properties of a biological structure; computationally evolve the biological structure to obtain an evolved descriptor; inverse-mapping the evolved description to real space to form an evolved structure design; and constructing the evolved structure. The evolved structure comprises stronger performance across the properties than the biological structure. In an example aspect, a method for constructing an evolved structure includes: removing sericin from a cocoon; forming a first solution from the cocoon with removed sericin; forming a silk fibroin powder from the first solution; dissolving the silk fibroin powder to form a second solution; and electro spinning the second solution based on the evolved structure design.
