There is convincing paleontological evidence showing that stromatolite-building phototactic prokaryotes were already in existence 3.5 × 109 years ago. Late accretion impacts may have killed off life on our planet as late as 3.8 × 109 years ago. This leaves only 300 million years to go from the prebiotic soup to the RNA world and to cyanobacteria. However, 300 million years should be more than sufficient time. All known prebiotic reactions take place in geologically rapid time scales, and very…

If recent strong evidence of fossil cyanobacteria in carbonaceous meteorites is accepted, then the LCC would have existed prior to the origin of life on Earth and the planet would then have been seeded with representatives of the three domains once it became habitable.
Darwin’s warm little pond revisited: from molecules to the origin of life
In this review, this review has concentrated on experimental and theoretical research published over the last two decades, which has added a wealth of new details and helped to close gaps in previous understanding of this multifaceted field.
Extremophiles may be irrelevant to the origin of life.
It is suggested here that while environments capable of supporting life may be common, this does not in itself support the notion that life is common in the universe.
The Nature of the Last Common Ancestor
The identification of the three major lineages is not an artifact based solely upon the reductionist extrapolation of information derived from the rRNA tree, but a true reflection of an ancient trifurcation.
Early life on land and the first terrestrial ecosystems
The rapid adaptations seen in modern terrestrial microbes, their outstanding tolerance to extreme and fluctuating conditions, their early and rapid diversification, and their old fossil record collectively suggest that they constituted the earliest terrestrial ecosystems, at least since the Neoarchean, further succeeding on land and forming a biomass-rich cover with mature soils where plant-dominated ecosystems later evolved.

The ease of formation of bioorganic compounds under plausible prebiotic conditions suggests that these molecules were present in the primitive terrestrial environment, and it is likely that the infall of comets, meteorites, and interplanetary dust particles, as well as submarine hydrothermal vent synthesis, may have contributed to prebiotics organic evolution.
3 Early Life on Earth and Analogies to Mars
The evidence for early life and its initial evolution on Earth is linked intimately with the geological evolution of the early Earth. The environment of the early Earth would be considered extreme by
Scenarios for the evolution of life on Mars

Many different locations on the primitive earth have been proposed as possible places for the origin of life. Experimental investigations of sea ice, in particular the studies of one author in the


Photosynthesis 3.5 thousand million years ago
Values of δ13C for sedimentary organic carbon strongly suggest autotrophic CO2 fixation, and the existence of large deposits of sedimentary sulfate is consistent with a photosynthesis dependent on reduced sulfur compounds for reducing power.
Origin and early evolution of photosynthesis
The evolutionary relationships of the reaction center complexes found in all the classes of currently existing organisms have been analyzed using sequence analysis and biophysical measurements and it is indicated that all reaction centers fall into two basic groups, those with pheophytin and a pair of quinones as early acceptors, and those with iron sulfur clusters asEarly acceptors.
Estimates of the maximum time required to originate life
The impact model suggests that it is possible that life may have originated more than once and the maximum time required for the origination of life is the time that occurred between sterilizing impacts just before 3.8 Ga.
Pre-biotic organic matter from comets and asteroids
About 20 g cm−2 intact organic carbon may have accumulated in the few hundred million years between the last cataclysmic impact and the beginning of life, which may have included some biologically important compounds that did not form by abiotic synthesis on Earth.

These Early Archean stromatolites suggest that phototrophs evolved by 3500 million years ago, and would indicate that nearly all prokaryotic phyla had already evolved and that proKaryotes diversified rapidly on the early Earth.
Cometary delivery of organic molecules to the early Earth.
A comprehensive treatment of comet-asteroid interaction with the atmosphere, surface impact, and resulting organic pyrolysis demonstrates that organics will not survive impacts at velocities greater than about 10 kilometers per second and that even comets and asteroids as small as 100 meters in radius cannot be aerobraked to below this velocity in 1-bar atmospheres.
Impact constraints on the environment for chemical evolution and the continuity of life
The frequency of giant terrestrial impacts able to stop prebiotic chemistry in the probable regions of chemical evolution is explored to suggest life probably could have originated near the surface between frequent surface sterilizing impacts.

The evidence that is currently available does not support the availability of ribose on the prebiotic earth, except perhaps for brief periods of time, in low concentration as part of a complex mixture, and under conditions unsuitable for nucleoside synthesis.

Impact frustration of the origin of life
Using a range of plausible values for the timescale for abiogenesis, the interval in time when life might first have bootstrapped itself into existence can be found for each environment.
