By the government guidelines for teaching "the Course of Study" change of lower secondary and upper secondary school, a new teaching unit "Creature Transition and Evolution" was added in lower secondary school science, and "Structure of Creature Evolution Process" was directed in upper secondary school biology. Currently, developing teaching materials in lower secondary and upper secondary school has been a considerable pressing issue. Therefore, we conducted a basic research on the evolution by using familiar Brachypterous grasshopper "Parapodisma setouchiensis". As a result, the character of color was specialized by geographic isolation border called abu river, and the smaller its body size gets, the higher the living altitude becomes. Accordingly, this species were considered to be effective in the studies regarding geographic variation, geographic isolation, speciation, adaptation and natural selection.
