Many animals are either diurnal (active during daylight) or nocturnal (active during night). What do the abilities of rods and cones to respond to different lighting conditions tell us about the niche of human beings relative to night and day?
What will be an ideal response?
Rods are responsible for scotopic vision, or the ability to see in dim light. Under ideal conditions, the human eye can see a single photon. The cost for this extraordinary sensitivity to light is in the clarity and color of the image provided by the rods. Rods do not provide any information about color, and they do not produce sharp images. Cones are responsible for photopic vision or vision in bright light. Photopic vision is sensitive to color and provides images with excellent clarity. Given that humans are normally awake during the day would suggest that we rely much more heavily on the fine details provided by our cones for the majority of our visual information.
