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:

back up your civ2 files, copy everything into your civ2 directory, and then:

leave the following files as is:
bio.txt 
bio.scn
bio.mp

remove the "bio" suffix from the names of the following files:
biogame.txt
biorules.txt
biounits.gif
bioicons.gif
biocity.txt

Make the following name changes:
biocity.gif --> cities.gif
biolabel.txt --> labels.txt

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 me, and are free to the 
public as long as they are not changed.  Have fun, y'all.
