The phrase 'Survival of the fittest' as a way of describing the mechanism of natural selection was coined by ______.
Herbert Spencer
Survival of the Fittest Phrase Origin Explained
The question asks about the origin of the phrase 'Survival of the fittest', particularly as it relates to the mechanism of natural selection.
While closely associated with Charles Darwin's theory of evolution by natural selection, the phrase itself was not coined by Darwin. It was introduced by another prominent thinker of the time.
Who Coined 'Survival of the Fittest'?
The phrase 'Survival of the fittest' was coined by the English philosopher and sociologist, Herbert Spencer.
Spencer used this phrase in his 1864 work, "Principles of Biology," where he drew parallels between his economic theories and Darwin's biological concepts. He proposed it as a way to describe what Darwin called "natural selection." Darwin later adopted Spencer's phrase in subsequent editions of "On the Origin of Species," though he still preferred "natural selection."
Analyzing the Options
Let's look at why the other options are not correct:
- Charles Babbage: Known as the "father of the computer" for his mechanical computing machines. His work was primarily in mathematics and engineering, not biology or sociology related to evolutionary theory.
- Louis Pasteur: A French chemist and microbiologist who made significant discoveries about vaccination, microbial fermentation, and pasteurization. His contributions were crucial to understanding germ theory and preventing diseases, not coining terms related to natural selection.
- Marie Curie: A Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two different scientific fields. Her work is in physics and chemistry, not evolutionary biology terminology.
Conclusion
Based on historical accounts, the phrase 'Survival of the fittest' was introduced by Herbert Spencer. While it became widely associated with Darwinian evolution, it originated in Spencer's writings.

| Term | Definition | Key Figure(s) |
|---|---|---|
| Natural Selection | The process where organisms better adapted to their environment tend to survive and produce more offspring. | Charles Darwin, Alfred Russel Wallace |
| Survival of the Fittest | A phrase describing the outcome of natural selection, implying those best suited to an environment survive and reproduce. | Herbert Spencer (coined phrase), Charles Darwin (adopted phrase) |
| Evolution | The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. | Charles Darwin, Alfred Russel Wallace, Jean-Baptiste Lamarck (earlier theories) |
| Adaptation | A trait that increases an organism's ability to survive and reproduce in its environment. | N/A (concept within evolution) |
Additional Information: Herbert Spencer and Social Darwinism
Herbert Spencer was a key figure in the development of sociology. He applied his ideas of evolution, including 'Survival of the fittest', not only to biology but also to social systems and economics. This application of evolutionary concepts to society became known as Social Darwinism, although Spencer's views predated Darwin's full theory and influenced it in some ways.
It's important to note that 'Survival of the fittest' in a biological context refers to reproductive success and the ability to pass on genes, not necessarily physical strength or dominance. An organism is "fit" if it is well-adapted to its specific environment and can successfully reproduce.
