Life arose on Earth about 3.5 billion years ago (perhaps as much as 3.9 billion years ago).


The story of Earth's life covers 86.7% of the scroll.


Stromatolites are the earliest known fossils (this one is 3.5 million years old).

Stromatolites are rock-like structures that were

Stromatolites were thought to have been extinct until forty years ago.

--- Charles Darwin
