Solution:
Fitness is the end result of the ability to adapt and get selected by nature. In an organism, the so-called fitness depends upon the inherited characteristics, so there must be a genetic basis for getting selected and to evolve. Some organisms in a population are better adapted to survive in an hostile environment.
