Assertion: Darwin's theory of natural selection was influenced by T.R. Malthus' theory of human population growth.
Reason: Malthus' theory highlighted the imbalance that can arise between population growth and the availability of resources.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
Darwin's theory of natural selection was influenced by T.R. Malthus' theory of human population growth. Malthus' theory highlighted the imbalance that can occur between population growth and resource availability. Darwin incorporated Malthus' ideas into his own theory, recognizing that population grows geometrically while resources grow arithmetically, leading to a potential scarcity of resources. Therefore, Malthus' theory provided an explanation for the influence on Darwin's theory of natural selection.
Option 1 is the correct answer.
