This is the first episode of a series about our amazing past, about the history of life on earth.

These videos don't pretend to be exaustive on such a complex subject.

If you want, feel free to consult these links... or to buy some good, updated book! ;-)

About timeline:

Note: don't be surprised if, reading N different sources, you'll find N different beginning/ending time for each period... scientists often have different opinions about these things!

About layers:

Many links will come with each episode!
