How is the peppered moth of England an example of natural selection?

Answer 1

The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.

Black moths were selected for when the trees turned black.

the moths with the high fitness were selected for

The black moths were more fit for survival, so their phenotype frequency increased.

Answer 2

Before the industrial revolution the mass of peppered moths were light in colour and blended into the light coloured tree trunks, those that were darker coloured were spotted by birds and other predators and were killed off donating to the success of the lighter coloured moths. When the industrial revolution began the pollution covered the trees in a darker layer, now on the contrary of the original scenario the darker coloured moths blended in and the lighter coloured moths were easily spotted. Thus pollution was the cause of the darker coloured moths being naturally selected. The damage of pollution was reversed in recent years and the moths have again returned to being mostly light coloured.

Answer 3

Peppered moths are an example of natural selection because of their environment. The area go through periods of producing either white or black ash. The moths match with their accordingly. If the it is mostly white than so are the moths ans visa versa.

Answer 4

The peppered moth story only provides evidence for genetic intrinsic computer programs (DNA) of different types of Flora and Fauna...in this case...moths. It does not give evidence for increase complexities of the original DNA and protein coupled systems (involving new organs or body plans). It does not show us how moths came into existence in the first place...the paleontological etiology of moths is NOT addressed by the peppered moths model. The potential for white and dark moths to be targeted by predators is based on contrasting variables of the moths to their background. NO NEW MOTH IS INTRODUCED...only a natural (conservative) process of elimination occurs...and the frequency of reproduction increases for the remaining types of moth. Evolution has NEVER been substantiated by experimentally derived evidence.

Answer 5

The main type of peppered moth is white with black specks, camouflaging it on white birch trees. However, there is a rare black form (around 5% of the population), which stands out on the white trees and is eaten by birds more often.

Now, in the Industrial Revolution, factories belched so much coal into the atmosphere that it stained the birch trees black. Now the white moths stood out, and the black ones were camouflaged. The white ones were eaten by birds, and the black ones survived to reproduce. In just a few years the black form had become the common one and just around 5% of moths was the white form!

After the Revolution coal output was cut back and the trees returned to normal. And what do you know, the moths adapted again, and the black form became rare again. The common-rare shift goes along with the environment, making sure the moth species as a whole does not die out. Survival of the best-camouflaged.

Answer 6

Prior to the industrial revolution, white peppered moths were far more common than dark, because they camouflaged on the light bark of trees better. After factories covered local trees in soot, the bark was made dark. This meant the dark moths had an advantage, and they quickly replaced most of the white moths.

Answer 7

The peppered moth is an example of natural selection as it adapted to industrial pollution by changing its color. Before the Industrial Revolution, light-colored moths were more common, but as pollution darkened tree bark, dark-colored moths became more prevalent as they had better camouflage. This shift in coloration over time reflects the process of natural selection favoring traits that increase an organism's survival and reproduction in its environment.

Answer 8

European peppered moths have, over time and as a direct result of the Industrial Revolution, change their collective coloration in order to blend with the new landscape.
