The Error of the Evolution
of Species
Functioning: Maintaining Natural Life Support Processes,"
written by 12 scientists 137 from various universities, American
and European experts have clearly shown that there is a di-
rect correlation between species numbers and efficiency. 138
To put it another way, species diversity means high pro-
ductivity. For example, seven years of research by Prof.
David Tilman and his team determined that in any given en-
vironment, an area made up of several plant species gives
more products than an equal area composed of only a few.
A field sown with 16 species of plant produces 2.7 times
greater biomass than a field sown with only one. 139
According to Professor Tilman, the reason for this is that
many species use the resources in the field more efficiently.
Every species in the ecosystem can be compared to a dif-
