How does fitness affect evolution?

Biologists use the word fitness to describe how good a particular genotype is at leaving offspring in the next generation relative to how good other genotypes are at it. … A genotype’s fitness includes its ability to survive, find a mate, produce offspring — and ultimately leave its genes in the next generation.

Is survival of the fittest a tautology?

Tautology. “Survival of the fittest” is sometimes claimed to be a tautology. … Furthermore, the expression does become a tautology if one uses the most widely accepted definition of “fitness” in modern biology, namely reproductive success itself (rather than any set of characters conducive to this reproductive success).
