Question

Fish that developed the ability to live out of water is one example of natural selection. Explain how another species has adapted via natural selection. Answer

Answer 1

Natural selection is illustrated by the darkening of peppered moths during the Industrial Revolution due to pollution and the evolution of antibiotic-resistant bacteria as a response to the overuse of antibiotics.

Step-by-step explanation:

Examples of Natural Selection

One compelling example of a species that has adapted via natural selection is the peppered moth during the Industrial Revolution in England. Before industrialization, the more common form of the moth had light coloring which blended in with the lichen-covered trees where they rested. However, as pollution increased and darkened the trees' bark, moths with a darker coloration, which were initially rare, became less visible to predators. This led to the darker moths surviving at higher rates and passing their genes to offspring. Over time, the population shifted to mostly dark-colored moths due to this selective pressure.

Answer 2

Step-by-step explanation:

Before the industrial revolution, most of the moth population had white wings. During and after the industrial revolution, the moth population has evolved to have a majority black population. This happened due to changing natural selection pressures. The black moths were able to camouflage in the ‘dark environment’ caused by soot from the industrial revolution. The moths were less linly to be preyed on compared to white moths that stood out in the ‘black’ environment. Over a generation, the allele for white-color, because it offered a disadvantage, becomes ‘weeded out’ of the population.
