biological fitness

Biological fitness refers to an organism’s ability to survive, reproduce, and pass on its genes to the next generation. It doesn't just mean being strong or healthy; it encompasses how well an organism is adapted to its environment. For example, a species that can find food, evade predators, and attract mates is considered more fit. Higher biological fitness often leads to more offspring, which helps ensure that advantageous traits continue in a population. In essence, it's about the success of an organism in contributing its genes to future generations within the context of its ecosystem.
