However, one mystery about multicellular organisms is why cells did not return back to single-celled life. “Unicellularity is clearly successful — unicellular ...Variation. In evolution, the fate of an individual depends on which features it has. Each human, for example, inherits a unique combination of thousands of different features, such as eye color, blood type and sensitivity to certain tastes.
