$8$ An important primate feature is forward$-$facing eyes, which allows for depth perception. Close one eye, and then close the other eye before answering the following questions.

a Draw a person's head from the top$/$superior view $($it could be just a simple circle$),$ and fill in the location of the eyes.

b Based on your range of vision after closing each eye, in your sketch draw lines from the eyes that show the approximate fields of vision for each eye $($you will have two lines going out from each eye$).$

c Shade in the area of overlap between the fields of vision. This is how depth perception is accomplished$-$from overlapping visual fields.
