When in Earth's history did life develop?
How long did it take for complex life to develop?
What can these answers tell us about the type of life we might find on other planets?

Guess when various kinds of organisms first developed in the history of Earth. Then reveal actual timeline of life. The early development of simple life and the relatively late development of complex life changes many people's ideas of what alien life may look like.
