Did You Know?

Many ancient myths end in a metamorphosis. As Apollo is chasing the nymph Daphne, she calls on her river-god father for help and he turns her into a laurel tree to save her. Out of anger and jealousy, the goddess Athena turns the marvelous weaver Arachne into a spider that will spin only beautiful webs. But natural substances may also metamorphose, or undergo metamorphosis. Heat and pressure over thousands of years may eventually turn tiny organisms into petroleum, and coal into diamonds. And the most beloved of natural metamorphoses (notice how this plural is formed) is probably the transformation of caterpillars into butterflies.
