So I would assume it is a feedback system where the eyes of the insect sees the color of the bark it is resting on and the body knows the color of the wings or sees the color of the wings having some contrast deemed dangerous and that starts a chain reaction ending in a genetic change that lowers the contrast to the bark,
The Point is that genetics determine colour for the rodents in the paper originally posted with the sensational Headline. There is no Change of colour in adult animals here (chameleons are different in that respect as are some other specialist species).
The whole Point is that the experimenters made a Connection between different genetic set-ups resulting in different coloured animals. The infromation however for the colour was there before the Experiment. What they did is to shift (by killing of the animals with the unfavourable colour) the Distribution of the infromation in the whole pool. So they "proved" natural selection. This was not the aim of the Research. The aim was to connect genotype and phenotype.
My Point is: The authors of the Research paper did some valuable contribution on science with a well done Research paper. The title of the paper : "Linking a mutation to survival in wild mice" is appropriate and tells the Reader what to expect, which is a quite sepcific information.
The journalists of the paper Scienec went one step wfurther by bringing in their Headline for the Abstract: How natural selection affects mouse coat Color. This is still covered by the paper but not the main Point. "Just" a side effect, which in itself would not have been sufficient to publish the paper at all.
The title of this thread is using "demonstrating Evolution in real-time" and that is plain wrong. The authors of the Research quite correctly don't make that Claim.
I tried to state the Facts and try to bring up a criterion which would cover the Headline. That would be the Observation of a new Mutation, which Shows an Advantage and is actually distributed in the gene pool, thus adding infromation to the System.
