Q. The concept of survival of the fittest was first advocated by ____:
Answer: Darwin
Notes: “Survival of the fittest” is a phrase originated in evolutionary theory, as an alternative description of natural selection. Herbert Spencer first used the phrase – after reading Charles Darwin’s On the Origin of Species – in his Principles of Biology (1864), in which he drew parallels between his own economic theories and Darwin’s biological one. Darwin first used Spencer’s new phrase “survival of the fittest” as a synonym for natural selection in the fifth edition of “On the Origin of Species by natural selection” published in 1869.
