Edward Wilson's latest book "The Diversity of Life" attempts to answer
the question of species number.  As I recall, some Norwegian workers
came up with an estimate of 5000 different "species" of bacteria in a
gram of soil.  Another gram of soil from a different location came up
with another 5000!  I'm not sure if the species concept is helpful in
the face of this stupefying diversity.  Perhaps the question we should
ask is what IS a species, anyway?
