The events during the primordial
era that led to the formation of precursors of
primordial cells (spherules) and cells were divided
into the following categories by Dickerson and
1. The first phase of superheated
Gases: The primordial gases underwent unending
changes in their atmospheric complexion and
proportion, followed by cooling.
2. The second phase of formation
of monomers: Coming together of primordial elements
to form small-sized substances, followed by the
synthesis of biological monomers such as amino
acids, sugars and organic bases.
3. The third phase of
polymerization: The aggregation (polymerization) of
small monomers into larger polymers, and then into
primitive protein and nucleic acid chains in an
aqueous environment to produce a primordial soup.
4. The fourth phase of
protobionts: Differentiation Within the Primordial
5. The segregation of Haldane's
soup into protobionts with a chemistry and an
identity of their own.
6. The fifth phase of the development of
Oxygen-Driven Energetics: An Intelligent Design
