<< Short Abstract
This book considers the question how complex systems suddenly emerge
during the course of evolution and why the long-winded evolution of
systems and species is interspersed with short phases of fast revolutions.
Based on an agent based view of complex systems, it describes how systems
become more and more complex, well illustrated with many examples for the
emergence of complexity. From ancient cultures to modern states and from
the earliest primitive organisms to self-conscious human beings, the text
explores the widest range of phenomena with the fewest possible principles.

I have suggested this model for
selection pressure:

As environmental adaptation increases, 
stabilizing selection increases and
directional and diversifying selection decreases

AND vice versa

As environmental adaptation decreases, 
stabilizing selection decreases and
directional and diversifying selection increases

This seems to suggest the reason why there 
are different speeds of change in different species.
