Unformatted text preview: (running speed for example), a graph like the one shown is often produced. We would get a similar bell-shaped curve if we plotted height, weight , performance on exams, etc. Some Variants are Better Some individuals are bound to be better than others. Perhaps their body structure allows them to escape predators better or to find food faster or to better provide for their young. For example, suppose that the faster-running animals diagrammed below are better able to escape predators than the slower ones. You would expect that more of the faster ones would survive and reproduce than the slower ones.
