Which concept describes the idea that specific environmental pressures can lead to the enhancement of particular traits in organisms?

The concept that describes the idea that specific environmental pressures can lead to the enhancement of particular traits in organisms is natural selection. Natural selection is a fundamental mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce in a given environment. This process means that these traits become more common in the population over generations.

For example, if a particular environment favors faster individuals (perhaps due to predation or competition for resources), then those individuals may survive longer and produce more offspring, leading to a gradual increase in the frequency of that trait within the population. The environmental pressures act as a "selective force," shaping the direction of change in the traits of a population over time.

The concept of selective pressure refers to the specific factors that influence an organism's chances of survival and reproduction, but it is part of the broader process of natural selection. Carrying capacity relates to the maximum population size that an environment can sustainably support and does not directly relate to the enhancement of specific traits. Evolution describes the overall process of change in the heritable characteristics of biological populations over successive generations, but natural selection is the specific mechanism driving that change in response to environmental pressures.
