Originally posted by rogue06 View PostEvolution is all about leaving the most progeny. When the trees got darker those with the genes that caused them to be darker thrived and quickly started out producing the lighter colored variety to the point that the former rapidly became the overwhelming majority. When the situation was reversed the lighter colored moths were the ones that thrived and the darker variety has become exceedingly rare. The genes for both dark and light coloring still exist in the over all population but it was the environment that decided which would flourish and prosper. If the genes for variation didn't exist then the population would remain stagnant and make evolution impossible
This is how evolution works.

Originally posted by Roy View PostNo, that's backwards. The dark allele is dominant. Two light moths can't produce dark offspring because they won't have any copies of the dark allele - unless a mutation occurs.

The industrial melanism mutation in British peppered moths is a transposable element
van't Hof et al
Nature, 534, pages 102–105 (02 June 2016)
Abstract: Discovering the mutational events that fuel adaptation to environmental change remains an important challenge for evolutionary biology. The classroom example of a visible evolutionary response is industrial melanism in the peppered moth (Biston betularia): the replacement, during the Industrial Revolution, of the common pale typica form by a previously unknown black (carbonaria) form, driven by the interaction between bird predation and coal pollution. The carbonaria locus has been coarsely localized to a 200-kilobase region, but the specific identity and nature of the sequence difference controlling the carbonaria–typica polymorphism, and the gene it influences, are unknown. Here we show that the mutation event giving rise to industrial melanism in Britain was the insertion of a large, tandemly repeated, transposable element into the first intron of the gene cortex. Statistical inference based on the distribution of recombined carbonaria haplotypes indicates that this transposition event occurred around 1819, consistent with the historical record. We have begun to dissect the mode of action of the carbonaria transposable element by showing that it increases the abundance of a cortex transcript, the protein product of which plays an important role in cell-cycle regulation, during early wing disc development. 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.
Selective bird predation on the peppered moth: the last experiment of Michael Majerus
Cook et al
The Royal Society Biology Letters, 8 February 2012.DOI: 10.1098/rsbl.2011.1136
Abstract: Colour variation in the peppered moth Biston betularia was long accepted to be under strong natural selection. Melanics were believed to be fitter than pale morphs because of lower predation at daytime resting sites on dark, sooty bark. Melanics became common during the industrial revolution, but since 1970 there has been a rapid reversal, assumed to have been caused by predators selecting against melanics resting on today's less sooty bark. Recently, these classical explanations of melanism were attacked, and there has been general scepticism about birds as selective agents. Experiments and observations were accordingly carried out by Michael Majerus to address perceived weaknesses of earlier work. Unfortunately, he did not live to publish the results, which are analysed and presented here by the authors. Majerus released 4864 moths in his six-year experiment, the largest ever attempted for any similar study. There was strong differential bird predation against melanic peppered moths. Daily selection against melanics (s ≃ 0.1) was sufficient in magnitude and direction to explain the recent rapid decline of melanism in post-industrial Britain. These data provide the most direct evidence yet to implicate camouflage and bird predation as the overriding explanation for the rise and fall of melanism in mothsLast edited by HMS_Beagle; 09-21-2018, 01:43 PM.
