Metamorphosis is the process that turns a caterpillar to a butterfly, a fry to a fish, and a tadpole to a frog. Animals have been metamorphosing for over 500 million years, from early crustaceans to the many fish, amphibians, and arthropods that do it today. Larvae, pupae, and adults are known in the fossil record, but the evolutionary history of this incredible life strategy is still mysterious.
In the news: a new tyrannosaur, early chameleons, giant turtles, and dinosaur temperatures.
