D) neural machinery for image processing

Question

Quizplus · Accepted Answer

The evolution of the eye likely began with the development of a simple, light-sensitive photo receptor that could detect changes in light and darkness. This was necessary for organisms to navigate their environment and avoid predators. Over time, this basic structure would have evolved into more complex adaptations, such as protective covers and internal structures, a depression to collect information about light, and neural machinery for image processing.
