Final answer:
Evolutionary fitness can be viewed as an organism's success in passing genetic material onto the next generation.
Step-by-step explanation:
Evolutionary fitness can be viewed as an organism's success in passing genetic material onto the next generation. In the context of evolution by natural selection, fitness refers to the relative ability of an organism to survive and produce fertile offspring. It is important to understand that evolution works on populations, not individuals, and the most fit individuals have more offspring, resulting in their traits becoming more prevalent in the population over time.
