Overcoming the loss of blue sensitivity through opsin duplication in the largest animal group, beetles

Abstract Opsin proteins are fundamental components of animal vision whose structure largely determines the sensitivity of visual pigments to different wavelengths of light. Surprisingly little is known about opsin evolution in beetles, even though they are the most species rich animal group on Earth...
