What are 3 ways one could find out if a particular animal has color vision?

Question

Think Critically

Answer 1

Most animals can learn to perform a simple task to get a treat. Researchers would try to train an animal to (for example) hit a blue button to get a treat, or avoid the red button because it makes a loud noise. For the experiment to be reliable they would have to make sure the color is the only difference -- they have to make sure the buttons don't smell different, or are always in the same locations, etc..

If the animals can learn this with black and white buttons, but NOT with red/blue buttons, that means they can't distinguish between those two colors.

One good rule for vertebrates is that good night vision equals poor color vision (and vice-versa). In birds, for instance, color vision is usually better than that of mammals except fot the few nocturnal ones, like owls, which have almost no color vision.

You can also dissect the eyes and count the ratio of structures known as cones and rods. Cones allow color perception but work poorly in low lighting while rods work best in low light but do not allow color perception. A high cone/rod ratio would indicate colour awareness while a high rod/cone ratio indicates good night vision but a lack of ability to perceive color.

Answer 2

i would get out my elephant rifle,Holland and Holland actioned 375 model 70 Winchester and slide the bolt back run a matched Norma load down the chambers release the safety and close on eye the scope is humongously in side the target area, the shot destroys all but the head and then i bring it to you and you tell me what is the three way to tell if the eyes are removed what they reveal about critervision
