|MadSci Network: Evolution|
The theory of punctuated equilibrium (PE) was put together to help explain the process of speciation and the absence of transitional forms in the fossil record. The main revolutionary point about the theory was that it explains why evolution appears to proceed by jumps and starts, that is mostly by long periods of stasis, with very little change, punctuated by short periods of drastic change (the formation of new species). You can find all the details of PE in almost any of the writings of Dr. Gould; he has published many books, some of which should be available in French translations.
