Detailed explanation-1: -According to Charles Darwin animals with variations better suited to their environment would have a better chance of survival and ability to breed. They would then pass on the favourable characteristics to their offspring. The Selective Agent is the environmental factor acting on the population.

Detailed explanation-2: -Any force in the environment that favors or disfavors traits is a selective agent. A force can be biological, like a predator, or physical, like temperature. Over time, populations subjected to different selective agents may become so different that they are no longer able to breed with one another.

Detailed explanation-3: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-4: -natural selection, process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution.

Detailed explanation-5: -Natural selection depends on the environment. Instead, it favors traits that are beneficial in a specific environment. Traits that are helpful in one environment might actually be harmful in another.
