Survival of the Fittest vs. Natural Selection
The biological concept of fitness is defined as reproductive success. In Darwinian terms the phrase is best understood as "Survival of the form that will leave the most copies of itself in successive generations. Herbert Spencer first used the phrase, after reading Charles Darwin 's On the Origin of Species , in his Principles of Biology , in which he drew parallels between his own economic theories and Darwin's biological ones: "This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called 'natural selection', or the preservation of favoured races in the struggle for life. Darwin responded positively to Alfred Russel Wallace 's suggestion of using Spencer's new phrase "survival of the fittest" as an alternative to "natural selection", and adopted the phrase in The Variation of Animals and Plants under Domestication published in Darwin has called 'natural selection', or the preservation of favored races in the struggle for life.
The idea that species adapt and change by natural selection with the best suited mutations becoming dominant. This expression is often attributed to Charles Darwin and, although it appears in the fifth edition of his Origin of Species , , it is there attributed to Herbert Spencer:. Herbert Spencer of the survival of the fittest is more accurate Spencer had published The principles of biology in In that he referred to 'survival of the fittest' twice:. Darwin has called 'natural selection, or the preservation of favoured races in the struggle for life'. By 'fittest', of course, Spencer and Darwin didn't have in mind the commonly used meaning of the word now, that is, the most highly trained and physically energetic.
You've probably heard it a million times in descriptions of evolution and natural selection. Charles Darwin even liked to say it. But the phrase "survival of the fittest" is wrong, and understanding why can help us better understand what it means to be human. Darwin uses the phrase "survival of the fittest" in chapter four of On the Origin of Species to describe the process of natural selection. But he did not coin the phrase. It was borrowed from English philosopher Herbert Spencer, who first talked about survival of the fittest in his Principles of Sociology.
When Charles Darwin was coming up with the Theory of Evolution , he had to find a mechanism that drove evolution. Many other scientists, such as Jean-Baptiste Lamarck , had already described the change in species over time, but they didn't offer explanations as to how it occurred. Darwin and Alfred Russel Wallace independently came up with the idea of natural selection to fill that void. Natural selection is the idea that species that acquire adaptations favorable for their environment will pass those adaptations to their offspring. Eventually, only individuals with those favorable adaptations will survive, which is how the species changes over time or evolves through speciation.
