A frog was observed to have too many legs, appearing deformed. This led to questioning why the frog was deformed, with potential explanations including genetic mutation, pollution, radiation, parasitic infection or other causes. A hypothesis was formed that increasing the number of parasites on a frog could cause deformities.
