Students have asked these similar questions
All primates have two eyes that face forward. This includes humans. Having two eyes is an evolutionary advantage and provides binocular vision, which means that two eyes are involved in the visual process. One of the advantages of having two eyes is the ability to perceive depth. Depth perception is achieved by:
a. analyzing the differences in the images falling on the left and right eyes
b. allowing light rays to converge and project an upside down image on the retina
c. the optic chiasm
d. changing the shape of the lens to accommodate the distance of an object
5c) Do you believe that experiments might be useful in determining the adaptive function of the pecten, if it indeed serves an adaptive function? Outline a simple experiment to see whether the presence of a pecten in the bird eye is an adaptation.
A) Would you conclude that the other primates are tasters or non-tasters? Why is this important? What role might the other differences between the species play in an evolutionary sense? Think of the role environment might play as well
