USA HISTORY

Detailed explanation-1: -Spencer’s first writings on evolution came in 1851, eight years before the publication of Darwin’s On the Origin of Species. And it was Spencer, not Darwin, who gave us the phrase “survival of the fittest, ” though Darwin would later use it in his writing.

Detailed explanation-2: -Charles Darwin not only did not coin the phrase “survival of the fittest” (the phrase was invented by Herbert Spencer), but he argued against it.

Detailed explanation-3: -While the phrase “survival of the fittest” is often used to mean “natural selection", it is avoided by modern biologists, because the phrase can be misleading. For example, survival is only one aspect of selection, and not always the most important.

Detailed explanation-4: -The Principles of Biology by Herbert Spencer (1864) looked at biology in terms of themes, such as Function, Adaptation and Variation. In this book Spencer introduced the expression ‘survival of the fittest’, in the sense of ‘the most appropriate to its environment’.

Detailed explanation-5: -Darwin proposed the theory of natural selection. But Herbert Spencer coined the term survival of the fittest after reading Darwin’s work. Q.
