Most of these are in species that are experiencing some sort of extreme environmental disturbance, such as invaders that have been released into a novel habitat or plants that rapidly adapt to the toxic soil of mine tailings. All of these examples show us that substantial evolutionary change can happen rapidly. bbb[b]They suggest that natural selection, rather than being a slow and gradual shaper of species, is most evident in brief bursts of change following major disruption.

> The rest of this article simply repeats what we have been saying for years: natural selection doesn’t create anything, random mutations don’t explain major novelties etc. The article does not offer any explanation for HOW novelties arise – it only points to dramatic changes in the environment as the factor that drives the changes. The author doesn’t mention your God’s preprogramming or dabbling, and she doesn’t mention Shapiro’s theory of natural genetic engineering (i.e. through the intelligent cell). All she really has to offer is confirmation of Gould’s theory of punctuated equilibrium, though she doesn’t mention him either - unless you've edited him out.
