Question

Darwin's theory of evolution fails to explain:

• A. Role of environment
• B. Origin and transmission of variations
• C. Overproduction
• D. Survival of the fittest

Answer 1

The correct option is B Origin and transmission of variations

• Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
• Also called as Darwinian theory, it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance when Charles Robert Darwin published,
• 'On the Origin of Species', including concepts which predated Darwin's theories, but subsequently referred to specific concepts of natural selection, the Weismann barrier or in genetics the central dogma of molecular biology.
• Darwinism offered no satisfactory explanation for the source of new genetic information from which natural selection could select.
• Bergson's theory proposed a non-Darwinian mechanism to produce new genetic information that, in turn, allowed well documented mechanisms, including natural selection, to function.
• So, Darwin theory fails to explain origin and transmission of variations. Thus, the correct answer is option B.
