Catastrophe Theory

I have just begun reading the book
An introduction to catastrophe theory
by P.T. Saunders
Cambridge University Press, 1980.

Catastrophe theory studies discontinuities,
singularities, and nonlinearity, most notably
in theoretical biology.

I am hoping that it might help me explain
my instigation of sudden evolution to
atheists, by my flapping of my higher
dimensional butterfly wings, if I am ever
successful. I am reporting on progress
on alt.religion.druid .

Do you know of any advances in catastrophe
theory/chaos theory since 1980 that I should
know about, and if so can you point to any
references available online?
