Natural selection the changing based on the environment, this produces an organism that is better suited to the environment. Some reasons for adaption of individual organelles include physical environments; precipitation and soil conditions or for biological reasons; diseases, competitors, or animals wanting to eat them. Natural selection will take many individual mutations that have been create due to a threat to be transferred to the rest of a species in a given environment. This creates genetically distinct populations known as ecotypes. Natural selection is acting on random variation that chooses the most favorable and inheritable mutation, these organelles will increase their chance to survive and to reproduce.
