SSC Stenographer 2026 PYQ — Question 148

The theory of evolution, first systematically articulated by Charles Darwin, provides a comprehensive explanation for how species gradually change and diversify over time through the process of natural selection. Organisms possessing traits that are better adapted to their specific environments are more likely to survive, reproduce successfully and pass these advantageous traits on to subsequent generations. Over extended periods, minor variations accumulate, leading to remarkable adaptations and the emergence of entirely new species. Extensive evidence supporting evolutionary theory comes from the fossil record, comparative anatomy and modern genetic studies. Evolutionary principles illuminate the vast diversity of life, the intricate relationships among organisms and the development of complex biological traits. Although initially controversial, the concept of evolution is now widely accepted within the scientific community and serves as a foundational framework in biology, medicine and ecology. Understanding evolution enables humans to fully appreciate the profound interconnectedness of life and the natural mechanisms driving ongoing biological change.
Organisms with traits better suited to their environment are more likely to _____.
