Viewed within the context of Darwin’s theory of natural selection and evolution, the English mottled moth is a fascinating example of the impact of change on a species. One can note how vivid the concept becomes when it implies the instability and specificity of the environment and of observation. A change in lichen coloration in a rural landscape, along with the negative impact of the Industrial Revolution, could have prompted the scientific community to consider natural selection. Over time, the population recovered, but with a darker-winged phenotype to help camouflage itself from predators in the new environment.
Natural selection favored the darker species, as they had a much better chance of survival. It is also worth noting the decisive role of environmental pressure, which is noticeable in this case. It determines the formation of the characteristics of members of the species and genetic change over time, which is the driving force behind the process. In other words, all moths with lighter wings perished while the darker version continued to survive and reproduce, replacing the population.
In addition, the nature vs. nurture debate can be simplified when considering the example of the speckled moth. It is further emphasized by the genetic mutation that caused the darkening of the wings, but was created by nature. At the same time, the actual prevalence of the trait grew strongly as a result and became universal because changes in conditions – nurture – made it preferable.
It is thought-provoking, yet it logically describes the peculiarities of the world’s existence within the framework of Darwin’s theory. Interdependence is present and can be confirmed by other examples and manifestations of evolution and change, the nuances of which are evident in the new environmental camouflage need. The evolutionary trajectory of a species is shaped precisely by the union of these factors and may really be the key to comprehending the world.
