One of my favorite books is Maps of Time, An Introduction to Big History by David Christian.

The DVD series by the Teaching Company’s Great Courses series is equally good as Mr. Christian leads 13 lectures based on the book.

He covers everything from the Big Bang, life on Earth to the rise of humanity.

He describes the eight generally agreed to “layers of complexity:”

1)     the universe;

2)     stars;

3)     the chemical elements;

4)     Earth;

5)     life;

6)     species;

7)     agriculture; and

8)     the modern revolution.
