New spheres of knowledge on the origin of life

The shape of a cell affects its physical and chemical properties. Different cell types have developed different shapes to enable effective functioning. But what shape were the very first cells, as life began to evolve? Cell shapes imaged by SEM. A Single-cell images of the Ori in both glucose and OAVs. B The six  lineages evolved in either glucose or OAVs (C) are shown on two size scales. Scale bars are indicated.  The upper and bottom panels in (C) indicate the lineages evolved...
