The Bacteria and Archaea are made up entirely of microorganisms; the Eukarya contains plants, animals, and microorganisms such as fungi and protists. Furthermore, we revisit central questions regarding the process of eukaryogenesis and discuss what can currently be inferred about the evolutionary transition from the first to the last eukaryotic common ancestor.

Stromatolites can be fossilized, and when cut open, there are sometimes layers or fossilized cyanobacteria inside, protected by the stromatolite. Prokaryotes and eukaryotes vary in several important ways - these differences include structural variation - whether a nucleus is present or absent, and whether the cell has membrane-bound organelles, and molecular variation, including whether the DNA is in a circular or linear form. The Archaeal Roots of the Eukaryotic Dynamic Actin Cytoskeleton USA 91, 16091613 (1994). Unlike the eukaryotic nucleus (which is surrounded by a nuclear envelope) the nucleoid is membrane-less, so the DNA is free-floating in the cytoplasm. & Embley, T. M. The primary divisions of life: a phylogenomic approach employing composition-heterogeneous methods. Bacteria are amongst the simplest of organisms - they are made of single cells.
