During the industrial revolution with an increase in the burning of coal and production of soot, the black form of the peppered moth was dominate. Natural selection favored the black form in an environment that was polluted.

Predators of the peppered moth include flycatchers, nuthatches, and the European robin. Like most moths, peppered moths avoids predators that hunt in daylight by flying at night and resting during the day.

Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. characterise the underlying genetics controlling the physical appearance of this moth,” he said. “It’s a graphic example of rapid evolutionary change.

Which type of moth do you think was more common before the 19th century, when most trees were light in color? The dark moth was more common before the 19th century and the light, speckled moth became the most common when all the trees took on a light color.

When the environment changed, due to pollution, the moth population shifted because light-colored moths became easier to see so they were eaten more often. Organisms that survive have a better chance of reproducing so the population continues to grow.

Q. Why did the population of peppered moths in England change from the light variation to the dark variation after the Industrial Revolution? The soot from industrial revolution caused the light peppered moth to fly away, and only the dark variation was left.

Wing-color changes in peppered moths are a common example of what scientists refer to as natural selection. In it, organisms develop random mutations. Some of the gene changes will leave individuals better suited — or adapted — to their environment. These individuals will tend to survive more often.

Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival.

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Natural selection occurs if four conditions are met: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual.
