Which term describes the process where the best-adapted organisms survive?

Explanation:
Natural selection is the mechanism by which the environment favors individuals with heritable traits that enhance survival and reproduction. Those fitter individuals leave more offspring, so over generations the advantageous traits become more common and the population becomes better suited to its surroundings. While competition for resources can create pressure, the key idea is that differential survival and reproduction due to heritable variation drives evolutionary change. Adaptation refers to the trait itself that improves fitness, not the process, and fossils are records of past life, not the mechanism by which survival is determined.
