Good question. People like to put things into categories to keep things organized. The living world doesn’t always fit neatly into those categories. Development of babies into adults is a good example of trying to make categories.


Think about a baby horse, cat, or dog. If you saw a picture of one, you could tell that it was a foal, kitten, or puppy, even if you didn’t know how big it was. Their heads are big compared to their bodies. Their eyes are big for their heads. They have higher foreheads and smaller noses. But these are not huge differences. Basically, mammals just get bigger as they develop. Their proportions—the size of one part compared to another—change. But they do not add whole new parts.


People wanted a different word for extreme changes, like a caterpillar into a butterfly, or a maggot into a fly. This is called complete metamorphosis. A crawling thing with a big body and many small legs becomes a flying thing with 6 long legs. The animal’s entire body is re-arranged.


Some things are in between. For example, crickets and beetles start off without wings. They look different from their parents in other ways, but those differences are not huge, like a caterpillar turning into a butterfly. This is called incomplete metamorphosis.
