a. an individual's reproductive success
In the evolutionary sense, fitness refers to the ability of an organism to pass its genes on to the next generation. Specifically, it's about an individual's reproductive success compared to other individuals in the population. This concept is central to natural selection, which is the process through which characteristics that enhance reproductive success become more common in a population over time. An organism is considered "fit" if it is successful in reproducing and if its offspring also survive to reproduce.
