TL;DR: It is found the genetic basis for visual senescence is distinct from that which determines variation in life span, and genes shaping early development of the nervous system, in particular the visual system, also contribute toSenescence at later age, demonstrating that senescences is part of a genetic continuum throughout the life span.
