It might sound tautological, but fitness is pretty much defined as 'being more likely to survive - and reproduce'; fitness is surviving and survival goes to the fittest. This is a trite way of citing Richard Dawkins' theory of the replicator to describe fitness. Fitness is a property of being able to carry one's genes to a later generation. Fitness is result of the individual properties and how well the individual can get along in the environment that it finds itself, in comparison to other individuals who might be competing for resources in that environment. There is no concrete definition of fitness. Fitness can mean size and strength, or lightness and resilience, short or long life.
