Very interesting! It's too much to digest all at once but his summary of simulation experiments on p240 of http://demo.cs.brandeis.edu/papers/watson_thesis_2002.pdf seems to show the same kind of step transition I found empirically in the G.tumida transition http://www.synapse9.com/GTRevis-2006fin.pdf, employing mechanisms not incompatible with those I proposed, fitting the logical necessities for the evidence of punctuated equilibria by providing a means for comprehensive change by a rapid process with a smooth start and end...
