NEET BIOLOGY

Detailed explanation-1: -Light-colored moths mutated into dark colored moths. Light-colored moths began to die due to overpopulation. Light-colored moths were less favored for survival in the new environment. Light-colored moths began to turn black because of factory pollution.

Detailed explanation-2: -As the trees darkened with soot, the light-colored moths were easier to see. They were eaten by birds more and more, while the rare dark colored moths blended in better on the darker trees. This made the dark colored moths have a higher survival rate.

Detailed explanation-3: -Genetic Changes Moths passed their color to the next generation. Eggs from light moths developed into light moths and dark moth eggs turned to dark adults. The dark color was caused by a mutation in the DNA of a single moth, and the mutated gene had been passed to all its offspring.

Detailed explanation-4: -Scientists have discovered the specific mutation that famously turned moths black during the Industrial Revolution. In an iconic evolutionary case study, a black form of the peppered moth rapidly took over in industrial parts of the UK during the 1800s, as soot blackened the tree trunks and walls of its habitat.

Detailed explanation-5: -How are the peppered moths turning from light colored to dark colored an example of natural selection? Dark moths had a higher chance of survival, longer lives, and more time to reproduce so eventually there were more.
