The correct answer to the question "What is fitness (in terms of evolution)?" is:
D. The relative ability of an organism to survive and reproduce
Explanation:
1. Fitness, in terms of evolution, refers to the relative ability of an organism to survive and reproduce in a given environment.
2. It is not solely about being large and muscular (option A) or the ability to bench press a specific weight (option C).
3. Fitness is a measure of an organism's genetic contribution to the next generation based on its ability to adapt to and thrive in its environment.
4. Organisms that are more fit have a higher chance of passing on their genes to the next generation, thus influencing the population's genetic makeup over time.
5. Option B is incorrect because fitness is context-dependent, meaning that what makes an organism fit in one environment may not necessarily apply to other environments.
In summary, fitness in evolutionary terms relates to an organism's ability to survive and reproduce successfully in its specific environment, impacting its genetic contribution to future generations.
