... Our findings fill a substantial knowledge gap in the iconic example of microevolutionary change, adding a further layer of insight into the mechanism of adaptation in response to natural selection. The discovery that the mutation itself is a transposable element will stimulate further debate about the importance of ‘jumping genes’ as a source of major phenotypic novelty.

Oo oo nailed it -- door #1 in Message 45 in Iconic Peppered Moth - gene mutation found:
1. an inactive gene section is moved into an active section of the genome and goes to work, ...
See -- it really was a "built-in" gene and it just needed the right recombination of the genes to become a realized phenotype ...

and Population Ecology
Thanks Genomicus for an excellent topic that I have been interested in for some time. Hopefully I can tweak it back to your topic ...
Particularly appropriate as I am reading a book gleaned from my dads library when we sold the old mansion ...
An Introduction to Population Ecology
G. Evelyn Hutchinson
New Haven and London
Yale Press 1978
I'm through chapter 1 so far, and I ran across this section:
F.E.Smith was my dad, and I remember visiting his office at UofM and seeing the tanks of daphnia. This paper was published in 1963, so I was still in High School. Several of the other references involve people we knew (Larry Slobodkin for example parties and annual department picnics. Another paper dad did with Larry is "Why the Earth is Green" ... good times.
My point here is that population biology\ecology deals with mechanics of growth\spread and limitations on that growth\spread in the population.
I have also been considering species as individual units for evolution in ecologies, and these 'logistic' type curves would also be applicable to species diversity in a specific ecology. When an extinction event causes an vacancy in an ecology the number of species would diversify rapidly and first and then slow down until they reach an equilibrium number of species that fill the niches. Island biogeography also comes back to this with a limitation on the number of species that can exist within a specific ecology. This also brings in the "Why the Earth is Green" paper.
Enjoy
