Survival of the fittest is the flawed quote, usually used by those with supremacist conceptual frameworks (that there can be an objective “better”, etc). This shows up a lot in fiction, where the quote is used as justification for cruelty, atrocities, and the like.
IMHO, the much better quote is:
> It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.
