Asked in Premeth Test 3 — The Cell, Evolution and Enzymes (5 March 2025) 2025Moderate

Darwin's theory mainly focuses on:

Correct answer: C. Arising of new species

  • A. Origin of life
  • B. Extinction of individual organs
  • C. Arising of new species
  • D. Formation of organisms

Explanation

Darwin's theory of evolution by natural selection primarily focuses on how new species arise through processes that increase the prevalence of advantageous traits within a population over time. These changes can eventually lead to the emergence of new species. The other options, such as the origin of life or the extinction of organisms, are not central to Darwin's theory. The formation of organisms is a topic explored by developmental biology, not evolutionary theory.

About Darwinism

Darwinism explains evolution through inherited variation, competition for limited resources, survival and reproduction of better-adapted organisms, and natural selection over generations. It is distinguished from Lamarckism because Darwin's explanation depends on selection acting on existing heritable differences, not the inheritance of acquired characteristics.
