Abstract

Two very typical bacterial shapes are the coccoid and the rod-shaped bacteria: the spherical and the cylindrical. Their abundance suggests that both are very effective growth forms and that they probably are simpler than other shapes to generate. Moreover, it can be argued that one or the other might have been the first member of the Domain of Bacteria. It is argued that, probably, the first bacterium was a Gram-positive bacillus.
