Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles.

In such a manner, the "labor" that a cell has to perform is divided among its organelles.
When a small populations' gene frequencies are changed drastically by chance alone it is called a genetic drift
