How does the British peppered moth support the theory of natural selection?

The Peppered moth avoids predation by using camouflage to blend int to tree bark. It was originally white with black spots. However in the industrial revolution when the local trees were blacked by soot from the factory chimneys, a black variant with white spots became prevalent in these regions.
In the areas of pollution the black version blended in and the white stood out so natural selection changed the appearance of the population in these areas.

What modern evidence is used to support evolution?
The branches of genetics, paleontology, observed natural selection and speciation all support evolution. Examples: (Genetics) Human chromosome 2 resulted from a fusion of two ancestral chromosomes. (Paleontology) Evolution of the horse. (Natural selection) Observed in Peppered moths. (Speciation) The Hawthorn Fly
What did Charles Darwin used the least to support natural selection?
yes
Why do you think Darwin considered the phrase the struggle to survive an appropriate description of natural selection?
Because in the wild there is a struggle for existence as more organisms are born than there are resources to support them. Thus, there is a wide variety of traits expressed by these many organisms and some of these traits confer survival and reproductive advantages which is what natural selection is selecting for.
Did Charles Darwin has scientific proof of his evolution theory?
Scientists did not prove things then anymore than they prove things now. Evidence, masses of converging evidence support the theory of evolution by natural selection. Darwin, in his day, had much evidence to support his theory. All the way from artificial selection to island biogeography. Since that time the theory has moved on to where it is no longer just Darwin's theory, but modified and supported with so much evidence that the theory became the bedrock of biology.

What factors support evolution-?
As we currently understand it, evolution happens if: - There are populations of organisms reproducing with variation - Those variations are inherited by offspring - More offspring is produced than can comfortably subsist in the habitat - Offspring therefore compete with one another for resources and mating opportunities - Variant inherited traits affect their ability to compete.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

yes
Who is the scientist that collected so much information to support natural selection in 1809?
Charles Darwin, the creator of the theory of natural selection, was born 1809.
How do the peppered moths support the theory of natural selection?
One of those that caught my attention was the evidence of peppered moths changing their color from light to dark due to industrial pollution. This supposedly shows how natural selection can change a species into another type, and eminent scientists have emphasized the importance of this supposed proof of evolution.Professor John Maynard Smith stated: "We should expect to find the most rapid evolutionary changes in populations suddenly exposed to new conditions. It is therefore natural that one of the most striking changes which has been observed in a wild population . . . is the phenomenon of 'industrial melanism,' the appearance and spread of dark forms of a number of species of moths" (The Theory of Evolution, 1966, p. 137).
Why is Darwin idea about natural selection considered to be a good idea?
Because there is a large body of evidence to support it.
By studying the nucleotides in DNA you get support for the theory of natural selection from observing that?
Life has a great potential for creating diversity.
Darwin proposes that all species of the natural world are in a constant state of evolution whereby natural selection plays a pivotal role in the survival of species Do you agree with this theory of yo?
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
Do you believe that this evidence gives support to the theory of evolution?
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
Why does the presence of extinct and transitional forms in the record support the pattern component of the theory of evolution by natural selection?
supports hypothesis that species have changed over time.
How does natural selection enable populations to grow?
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
