Answer Details

The phenomenon whereby some organisms get established in an environment after struggling for existence by taking advantage of some special features possessed by the organism is called natural selection. Natural selection is the process by which organisms with advantageous traits or characteristics are more likely to survive and reproduce in a given environment compared to those with less advantageous traits. As a result, the advantageous traits become more common in the population over time, leading to the evolution of new species. This process is driven by competition for resources and other environmental pressures, such as predators or disease, that favor certain traits over others.
