When organisms are “naturally selected” it means that they were born more adapted to their environment than others might be. When these more “fit” organisms reproduce, their traits are carried on to some of their offspring. As this trend continues over time, the population will be more adapted to their surroundings. A population going through this kind of trend results in the population being very different than it used to. This is the population evolving over time and changing.
