Evolution has always been a subject of questioning discussion ever since Charles Darwin established the theories of Natural Selection and Descent with Modification. According to Darwin, some animals were born with certain characteristics that became advantageous for their particular environment. As time passed, however these organisms modified some of these physical characteristics that they were born with in order to survive in their particular environment. This modification allowed the organisms to succeed in their environment and as a result, able to pass down this modification to their descendants. However, due to the nature of our world, we are always evolving in order to match our surroundings that continue to change in order to survive.

beutularia carbonaria who have black wing coloring are evolving back to the normal white with black specks across their wings coloring. However, the need to adapt to the decreasing of air pollution enforced by regulation made to clear industrial and other human contamination from the early industrial revolution. In how location is a major factor to why the peppered moths had to change a phenotype to adapt to their changing environment (Richardson, Urban, Bolnick et al. 2014). As for the selection and gene flow of how the peppered moths were able to survive in a changing environment are examples of how natural selection had to occur for the peppered to undergo a genetic mutation (Saccheri, Rousset, Watts et al. 2008). As well, the decrease of sulfur dioxide within the air reduces the phenotype within the moth to revert back to a lighter color (Grant, Cook, Clark et al. 1997). These are some of the effects to the decreasing of melanic moth, some causes of the decrease of melanic is air pollution, increase of lichens and being vulnerable to predators. …show more content…
Once in pre-industrial England, peppered moths were dominated by light colored phenotype, at the time it was an advantage of protection on tree cover lichen against predators. As the industrial period occurred there was more pollution due to the newly built factories and over production. Causing the areas surrounding trees to be covered with soot, this environmental change resulted in the increase of blacked carbonaria peppered moths. This was tested by many and in result came to the conclusion that a shift within a phenotype frequency was changed to benefit light colored peppered moths on their fitness survival against predators (Richardson et al. 2014). Currently with the decrease of pollution due to the help of air regulation trees are being able to reduce the soot layer on their bark. Causing the carbonaria peppered moth to decrease because it is now no longer an advantage to have a dark color phenotype allowing them to match the now rich covered
