Biosignatures and structures in the geological record indicate that microbial life has inhabited Earth for the past 3.5 billion years or so. Research in the physical sciences has been able to generate statements about the ancient environment that hosted this life. These include the chemical compositions and temperatures of the early ocean and atmosphere. Only recently have the natural sciences been able to provide experimental results describing the environments of ancient life. Our previous… 

Characterization of Reconstructed Ancestral Proteins Suggests a Change in Temperature of the Ancient Biosphere

Experimental data supports the idea that only thermophilic ancestors survived the catastrophic increase in temperature of the biosphere that was likely associated with meteorite impacts during the early history of Earth.

Resurrecting ancestral genes in bacteria to interpret ancient biosignatures

The ancestral sequence reconstruction of the beta-carbonic anhydrase protein is presented here, and how carbonic anHydrase proteins meet the selection criteria for reconstructing ancient biosignatures in the laboratory is assessed, which is termed palaeophenotype reconstruction.

Parallel adaptations to high temperatures in the Archaean eon

It is shown that both rRNA and protein sequences analysed with advanced, realistic models of molecular evolution provide independent support for two environmental-temperature-related phases during the evolutionary history of the tree of life.

How to resurrect ancestral proteins as proxies for ancient biogeochemistry.

Paleophenotype reconstruction as a window into historic biological states

Good design of revenant gene studies introduces new and interesting problems in the selection of genes, biosignatures, and modern host organisms, which should be understood as part of the next step in advancement of evolutionary methods.

Reconstructed ancestral enzymes suggest long-term cooling of Earth’s photic zone since the Archean

The results suggest that Earth's surface temperature decreased over geological time from ∼65–80 °C in the Archean, a finding consistent both with previous isotope-based and protein reconstruction-based interpretations and with ancient surface-environment paleotemperatures.

On the origin and evolution of thermophily: reconstruction of functional precambrian enzymes from ancestors of Bacillus.

The reconstruction of the structurally complex core metabolic enzyme LeuB from the last common ancestor (LCA) of Bacillus using both maximum likelihood (ML) and Bayesian inference demonstrates that reconstruction of complex functional Precambrian enzymes is possible and can provide empirical access to the evolution of ancient phenotypes and metabolisms.

The molecular signal for the adaptation to cold temperature during early life on Earth

The unknown nature of the phylogenetic signal that informs ancestral sequence reconstruction to support the conclusion that the ancestors of the bacterial and archaeal domains were thermophilic organisms which were adapted to hot environments during the early stages of the Earth is investigated.

Engineering ancestral protein hyperstability.

Comparison between evolutionarily related resurrected ancestral proteins emerges as a simple approach to expand the capability of ancestral reconstruction to search sequence space for extreme protein properties of biotechnological interest.

Inferring the palaeoenvironment of ancient bacteria on the basis of resurrected proteins

This study resurrects candidate sequences for elongation factors of the Tu family found at ancient nodes in the bacterial evolutionary tree, and measures their activities as a function of temperature to suggest that the ancient bacteria that hosted these particular genes were thermophiles, and neither hyperthermophiles nor mesophiles.

A palaeotemperature curve for the Precambrian oceans based on silicon isotopes in cherts

It is shown that the silicon isotopic composition of cherts more than 550 million years old shows systematic variations with age that support the earlier conclusion of long-term ocean cooling and exclude post-depositional exchange as the main source of the isotopic variations.

A genomic timescale for the origin of eukaryotes

BackgroundGenomic sequence analyses have shown that horizontal gene transfer occurred during the origin of eukaryotes as a consequence of symbiosis. However, details of the timing and number of

Early time estimates for methanogenesis support the consideration of methane, in addition to carbon dioxide, as a greenhouse gas responsible for the early warming of the Earths' surface and support most of the currently recognized higher-level groupings of prokaryotes.

Assessing the Accuracy of Ancestral Protein Reconstruction Methods

Surprisingly, it is found that methods such as maximum parsimony and maximum likelihood that reconstruct a “best guess” amino acid at each position overestimate thermostability, while a Bayesian method that sometimes chooses less-probable residues from the posterior probability distribution does not.

This review summarizes a decade of research that finds that it may be possible to understand microbial biodiversity within hot spring cyanobacterial mats by using principles similar to those developed by evolutionary ecologists to understand biodiversity of larger species.
