Abstract
High school students were investigated to make clear their time images of future evolution. Ten popular creatures were selected ; a mankind, a moss, a sparrow, an ameba, a cedar, an ape, a frog, a cherry tree, a tangle and a mackerel-pike. Students were asked which of them would evolve to other creatures in future. Students were asked how long time length, which was need to evolve, were. Results are as follows. (1) Students thought that evolution could occur in a very short period. (2) They use systems of creatures to answer the questions. The systems had four subsystems, a mankind, a higher animal, a higher plant and lower being. (3) Students could not understand that beings are evolving.
