Is industrial melanism is stabilizing selection?
Industrial melanism is an example of directional selection, not stabilizing selection. In this phenomenon, environmental changes such as pollution cause a shift in the frequency of dark-colored individuals within a population, which increases their survival rates due to camouflage. Stabilizing selection, on the other hand, favors the intermediate phenotype, reducing the variation in a population.
What insect was found to have industrial melanism?
The peppered moth was found to have industrial melanism. This phenomenon occurred during the Industrial Revolution in England, where darker-colored moths were able to camouflage better against polluted, soot-covered tree trunks. As a result, the darker moths had a higher survival rate compared to lighter-colored moths.
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.
Example of artificial selection?
Think GMO crops. Not natural selection, we selected them artificially
Why is a dandelion an example of natural selection?
All modern lifeforms are examples of natural selection, since they are all the result of it.

What is the darkening of populations over time in response to industrial pollution?
Industrial Melanism
What organisms affected by industrial melanism?
peppered moth
When was Peppered moth created?
Peppered moths have not been "created" in the traditional sense. They are a species of moth that has evolved over time through natural selection and adaptation. Their coloration played a role in the famous example of industrial melanism during the Industrial Revolution in England.
What is Industrial melanism?
Industrial melanism is a phenomenon where organisms in a population have darker pigmentation due to environmental changes caused by industrial pollution. This adaptation helps them blend into their surroundings better, reducing their risk of predation. One famous example is the peppered moth in Britain during the industrial revolution.
What is the change that occurred in peppered moths is an example of what?
The change that occurred in peppered moths, where the dark-colored moths became more prevalent in polluted areas, is an example of industrial melanism. This phenomenon demonstrates how natural selection can drive changes in populations based on environmental factors, such as pollution causing the dark moths to be better camouflaged against soot-covered trees.
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.

Which is more rare melanism or albinism?
Melanism is rarer than Albinism
