This passage via a one cell is beneficial in that it lowers the chance of mutations from currently being handed on by way of many persons. As an alternative, the mutation is simply handed onto one particular unique.[forty five] Further more studies utilizing Dictyostelium discoideum counsel that this unicellular initial stage is very important for resisting mutations because of the necessity of high relatedness.
