Thanks, that sounds like it may have been a precursor to the late Stephen J. Gould's punctuated equilibrium model, although that was mostly a semantic exercise or spin-doctoring.

Chesterton was an adult convert to Catholicism and an ardent anti-evolutionist ;-)

Odd that you should call Gould's punk-eek "spin-doctoring"; I thought it was a fairly well-supported description of discontinuties in the rate of mutations and/or speciation.

...and as such, might cause problems with a simplified 'DNA clock' method of dating things. :-)

Cheers!

Well put.
