What survival of the fittest means?

Answer 1

AnswerSurvival of the fittest, or Social Darwinism, refers to the characteristics of the fittest members of a species (in terms of their ability to survive in a given environment and produce offspring) will be passed on and become more common in the species. It does not refer to the fitness of individual organisms, precisely, but rather to the fitness of the species as a whole.

Charles Darwin defined natural selection as relating to the members of the species who were the most successful in survival skills (ie finding food, avoiding enemies, living to adulthood were the ones who had children and so propagated the species with their genes).

It should be noted that the Charles Darwin didn't use the term 'survival of the fittest', it was coined by biologist, sociologist, and author Herbert Spenser in his Principles of Biology published in 1864, five years after Darwin's On The Origin of Species. He used the term in his discussion of Darwin's book.

In the context of 'survival of the fittest', the word 'fittest' means best suited to its environment.
