Humans and Squid Evolved Same Eyes Using Same Genes

This informational text resource is intended to support reading in the content area. The text discusses the evolution of the eye across different types of organisms. Eyes have evolved independently several times (such as in squid vs. humans), though all animals with eyes share the Pax6 gene, which is responsible for organizing the formation of a simple eye. The evolution of the Pax6 gene, particularly in how its RNA product is spliced, is responsible for the diversity of eye types, such as the camera eye in squid.
