Here's why:
* Overproduction refers to the biological principle where organisms produce more offspring than can realistically survive in their environment. This is a key component of natural selection.
* Other terms might seem close, but they don't quite fit:
* Reproduction is the general process of creating offspring, but doesn't specify the excess.
* Survival of the fittest is a consequence of overproduction, not the process itself.
* Natural selection is the overall process that favors those best suited to the environment, driven in part by overproduction.
Overproduction ensures that some offspring will inherit advantageous traits, leading to a population better adapted to its surroundings over time.
