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.
Info on all the new stuff is available on my site at 
http://www.castle.net/~cwmagee/civ2.html,
if you don't like to just dive in.

To install:
Copy everything into your civ2 directory, and then:

run 

Switch.bat

to return, use 

Return.bat

and play!

My sources include all of my college 
biology and paleontology texts, mail me if you really care.
All changes are copyright (c) 1996, 1997 me, and are free to the 
public as long as they are not changed.  Have fun, y'all.
