Aflight-type dishwasher has compartments

The answer is that a fight-type dishwasher has separate components, namely the pre-washing section, the main washing section, and the drying section. During the pre-washing process, utensils or kitchenware are soaked to loose any stubborn dirt stuck. While on the main washing section, frees the utensils and kitchenware from any stain or dirt. Lastly, at the drying section, the machine removes any residual bacteria by drying the utensil or kitchenware.

It is evolution, because we all have some of the same traits like eye color or shape or ears.
