Question

Explain Darwin's Theory of Natural Selection in Brief​

Answer 1

Answer:

The theory of natural selection was proposed by Charles Darwin. It explains that nature has its own way to eliminate the organisms which cannot survive. It states that in a population, there always exists a number of variations based on different combinations of traits, now carrying capacity of the environment are not unlimited. Hence, nature selects the best-suited organisms that have a greater chance to become parents for the next generation.The event of industrial melanism is one of the phenomena which explains the natural selection. There were a number of white coloured moths which camouflaged on the trees. The black coloured moths were easily visible. After the industrial revolution, due to the deposition of the soot on the trees, the white coloured moths were easily killed by the predators. This is a form of natural selection which favours the survival of the organism which can adapt to the surrounding.

Answer 2

• Charles Darwin proposed the natural selection hypothesis.
• It illustrates that nature has its own system for eliminating species that are unable to live.
• It asserts that there are always a number of variants in a population depending on different combinations of features, and that the environment's carrying capacity is not infinite.
• As a result, nature chooses the best-suited creatures with the highest possibility of becoming parents for the following generation.
• One of the phenomena that explains natural selection is industrial melanism.
• A lot of white-colored moths were hiding in the branches. The black moths were clearly visible.
• The white coloured moths were readily destroyed by predators after the industrial revolution because of the accumulation of soot on the trees.
• This is a type of natural selection that favours organisms that can adapt to their surroundings.
