According to Neo-Darwinism, which of the following is a case of evolution?
Correct answer: A. Reproductive isolation
- A. Reproductive isolation
- B. Infinite large population
- C. Environmental stability
- D. Both a and b
Explanation
Neo-Darwinism (Modern Synthetic Theory) explains evolution through the combined effects ofGenetic variation (mutation + recombination)Natural selectionIsolation, especially reproductive isolationWhen populations become reproductively isolated, gene flow stops. Over generations, different mutations accumulate in each group, causing genetic divergence and eventually the formation of new species - that is, evolution.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
