Key Concepts

Evolutionary Fitness

Evolutionary fitness is a measure of an organism's ability to survive and reproduce in its environment, thereby passing its genes on to future generations. It encompasses traits that increase survival and reproductive success, rather than physical strength or specific health metrics.

Reproductive Success

Reproductive success pertains to an organism's effectiveness in producing viable offspring. It is a key component of evolutionary fitness because only individuals who reproduce successfully contribute their genetic material to the next generation.

Natural Selection

Natural selection is the process through which organisms with traits that increase their evolutionary fitness are more likely to survive and reproduce. This mechanism drives the adaptation of species over time, favoring those traits that enhance survival and reproductive output.
