Butterflies change wing color in new Yale research
Date:8/5/2014

Yale University scientists have chosen the most fleeting of mediums for their groundbreaking work on biomimicry: They've changed the color of butterfly wings.

In so doing, they produced the first structural color change in an animal by influencing evolution. The discovery may have implications for physicists and engineers trying to use evolutionary principles in the design of new materials and devices.

The research appears this week in the journal Proceedings of the National Academy of Sciences.

"What we did was to imagine a new target color for the wings of a butterfly, without any knowledge of whether this color was achievable, and selected for it gradually using populations of live butterflies," said Antnia Monteiro, a former professor of ecology and evolutionary biology at Yale, now at the National University of Singapore.

In this case, Monteiro and her team changed the wing color of the butterfly Bicyclus anynana from brown to violet. They needed only six generations of selection.

Little is known about how structural colors in nature evolved, although researchers have studied such mechanisms extensively in recent years. Most attempts at biomimicry involve finding a desirable outcome in nature and simply trying to copy it in the laboratory.

"Today, materials engineers are making complex materials to perform multiple functions. The parameter space for the design of such materials is huge, so it is not easy to search for the optimal design," said Hui Cao, chair of Yale's Department of Applied Physics, who also worked on the study. "This is why we can learn from nature, which has obtained the optimal solutions in many cases via natural evolution over millions of years."

Indeed, the scientists explained, natural selection algorithms can select for multiple characteristics simultaneously which is standard operating procedure in the natural world.
