Ordinary Differential Equations. Seriously.

I once posted a sketch of a calculation detailing the effects of a very
weak selective pressure on the human larynx, showing that a meme could
cause a drastic phenotypic change [Neanderthal to Cro-Magnon] in less
than 2000 or 3000 years. A literal blink of an eye, on typically assumed
geological time scales.

Punctuated equilibria falls out of the same calculations that generate
Natural Selection from Ordinary Differential Equations at "large"
