The Physics and Biochemistry of Life
Life is herein defined as an aggregating force (negative entropic). It is responsible for the phenomenon of EMERGENCE. It is the force that evolved the replication of coded macromolecules. A force that can be described using open system based equations of the second law of thermodynamics, density dependent versions of the Lotka-Voltera equations, and modeled by dissipation driven adaptive organization.
The evolution of Life starts with ATOMS which arose through Baryogenesis, Stellar Nucleogenesis, and Merging Neutron Star based Nucleosynthesis. Polymerizations of hydrogen, phosphorus, silicon, carbon , and nitrogen lead to creation of Graphene , Buckyballs, and Complex Biochemicals. Mixtures of biochemicals evolved into Metabolic Networks consisting of GADV-Proteins, PAHs and subsequently Peptide-RNA polymers or RNA only . These polymers evolved within Montmorillonite Clay, Iron-Sulfur, and /or Zinc precipitated environments on proto-earth , planetismals, and inside cosmic spherules .
It is unknown if the Polymer worlds evolved from a metabolism first system , replicon first and/or hybrid solutions involving Tholins. Current evidence exists for the presence of life on Earth 4.2 Billion years ago. There are also theoretical suggestions that the Last universal common ancestor of cellular life (LUCA) had DNA sequences which would require an origin of the genetic code to have been at least 10 Billion years ago. (longer than the existence of earth)
Cellular Life responds to destructive forces (physical and biological) by activating mobile genetic elements to create protective /defensive proteins and RNA. Mobile Genetic Elements are agents of Darwinian variation and they interact with hosts, infectious predators and cosmic-climatic-geochemical events. Continuous interaction promotes consortia development between mobile elements and their hosts resulting in the evolution of complex organisms and ecosystems. Koonin’s model somewhat similarily views these forces as being driven by parasite/anti defense systems or the availability of resources “public goods”.
Life is suggested to go through Transitions that are influenced by Mobile Genetic Elements.
-
Transition 1 Evolution of Hairpin RNA/ prototRNAs and ProtoEnzyme Replicators into Replicator Consortia. These ancestral Proto – Pre – and ProCells may have existed inside Blok globules, Herbig-Haro objects, and Proplyd Pebbles. The consortia contained pre-tRNA/rRNAs and urenzymes ( aa Synthetases I and II) which physiochemically evolved the genetic code within their common compartments.
-
Transition 2 Self assembling Procell Consortia transitioned into LUCA/Akaryotes/Prokaryotes and Viruses.
-
Transition 3 Evolution of Unicellular Eukaryotes, from Prokaryotes and Viruses.
-
Transition 4 1.6 – 1.25 Billion years ago : Evolution of Autotrophic Eukaryotes (Archaeaplastida) from Heterotrophic Eukaryotes
-
Transition 5 Evolution of Multicellular Fungi, Archaeoplastida and Metazoa.
-
Transition 6 Evolution of Eusocial Organisms
-
Transition 7 Evolution of Language in Humans on Earth.
