Problem set 1:food and stalk-eyed flies Stalk-eyed flies (Cyrtodiopsis dalmannn have eyes at the ends of long stalks that extend horizontally from each side of the head. Longer eye spans (the combined lengths of stalks from tip to tip) enhance attractiveness to mates and success in competitive interactions. Is eye span affected by the quality of food that flies eat? To find out, researchers reared two groups of flies on different foods, then recorded each fly's eye span in millimetres. One group of flies was fed com (a high-quality food), while the other group of flies was fed cotton wool (a low- quality food). Each fly per group was reared singly, and therefore represents an independent sampling unit.
