What insect was found to have industrial melanism?
the moth
Is industrial melanism is stabilizing selection?
No, that would be more of a directional selection. Phenotypic change from a minor variant phenotype, black in this case, to the majority phenotype due to the environmental selection pressure of pollution on the moth phenotype.
What is an example of natural selection taking place?
Recent examples of natural selection include:The peppered moth's change in predominant colour during and after the industrial revolution.A number of experiments performed by Richard Lenski, in which he not only witnessed increased fitness due to adaptation, but also the emergence of new traits responsible for some of those increases.The nylonase bacterium, which adapted to an environment rich with industrial wastes.Kettlewell, H. B. (1973). The Evolution of Melanism: The study of a recurring necessity.. Oxford, England: Oxford University Press.See links.
Is a frog an example of natural selection?
no
Example of artificial selection?
Think GMO crops. Not natural selection, we selected them artificially

What is the darkening of populations over time in response to industrial pollution?
Industrial Melanism
What organisms affected by industrial melanism?
peppered moth
How did industrial melanism has affected moths?
The effects industrial melanism is that it has produced more dark-colored moths than lighter ones. It has changed balance of population between the two types since the lighter ones were killed by the sulfur dioxide brought about by industrial pollution. This is true specifically for the peppered moth or Biston bitularia.

What is Industrial melanism?
Industrial melanism is the darkening of the skin, feathers or fur of a group of animals that live in a soot-darkened region. The melanization takes place slowly over generations and increases the possibility of survival.

When was The Evolution of Melanism created?
The Evolution of Melanism was created in 1973.
Which is more rare melanism or albinism?
Melanism is rarer than Albinism
Can Florida panthers get melanism?
There has never been a confirmed case of melanism among cougars.
Is melanism possible in humans?
Melanism is an increased amount of black pigmentation. Melanism may be possible in humans but there has never been a case of it. It mainly affects animals such as the panther.
