A few notes on this scenario:

Most scenarios excerpt a period of time shorter than the usual run of
CIV2.  This one does the opposite.
This simulates the rise of life from its origins over 3.5 billion years 
ago to today's technology.  If you are not familiar with geology, 
it is useful to know that MA stands for Millions of  Years Ago.  It replaces
B.C. on the year display.
The rules changes include changes in the values for the terrain, so running
conventional scenarios with these rules may not work.  If you want
to play on a computer generated map, I suggest small land area 
and wet climactic conditions.  Since there are no sounds, I 
recommend playing with the sound effects off.  I also recommend
turning off the option that will flash to civilopedia when you make a 
discovery, since all of the technologies have been changed.

Have fun, y'all.
