Full origin of survival of the fittest →Frequently Asked Questions
What does 'fittest' actually mean here?
It means best fitted to the environment, not strongest or healthiest. Fitness in biology is measured by how many surviving offspring an organism leaves, so a small, well-camouflaged animal can be fitter than a large, powerful one.
What is the difference between survival of the fittest and natural selection?
Natural selection is the scientific mechanism: heritable traits that improve reproductive success become more common over generations. 'Survival of the fittest' is a slogan for it, and biologists tend to avoid the phrase because it invites the circular reading that whoever survives must have been the fittest.
Did Darwin invent the phrase?
No. Herbert Spencer coined it, and Darwin only adopted it in a later edition of On the Origin of Species as an alternative wording for natural selection.
