The title is ‘A new look at eye design’, presented by Simon Laughlin.

Zoom information: https://eng-cam.zoom.us/j/84204498431?pwd=Um1oU284b1YxWThObGw4ZU9XZitWdz09 Meeting ID: 842 0449 8431 Passcode: 684140

Summary: An animal invests resources in an eye’s optics and photoreceptor array to meet behavioural needs economically. Thus eyes are adapted to meet these needs using designs that inspire physicists and engineers and provide opportunities for biologists to discover how complicated organs evolve. We take a new look at eye design by asking a question that is commonplace in engineering, but has not been addressed by biologists; how should the space, materials and energy invested in an eye be allocated to optics and photoreceptor array? To provide answers we develop a new cost:benefit approach that uses optical, geometrical and physiological constraints to link investments to an eye’s ability to capture information from light. Our models and data analysis show that eyes are configured efficiently. Photoreceptor costs dominate and influence the structure of the entire eye by competing with optics for resources.
