The Stepwise Evolution of Early Life Driven by Energy Conservation

Open access
Ferry, J. G.·2006·Molecular Biology and Evolution

Abstract

Two main theories have emerged for the origin and early evolution of life based on heterotrophic versus chemoautotrophic metabolisms. With the exception of a role for CO, the theories have little common ground. Here we propose an alternative theory for the early evolution of the cell which combines principal features of the widely disparate theories. The theory is based on the extant pathway for conversion of CO to methane and acetate, largely deduced from the genomic analysis of the archaeon Methanosarcina acetivorans. In contrast to current paradigms, we propose that an energy-conservation pathway was the major force which powered and directed the early evolution of the cell. We envision the proposed primitive energy-conservation pathway to have developed sometime after a period of chemical evolution but prior to the establishment of diverse protein-based anaerobic metabolisms. We further propose that energy conservation played the predominant role in the later evolution of anaerobic metabolisms which explains the origin and evolution of extant methanogenic pathways.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Acetyl thioesters are the most probable entry point of phosphate into metabolism.

    “Acetyl thioesters are furthermore the most probable entry point of phosphate into metabolism [42,77,78].”

    From Early bioenergetic evolution (2013) · cites this paper as [78]

  • The WLP is the most ancient carbon fixation pathway known.

    “its suggested presence in the deep nodes in the tree of life is in agreement with previous work that has pointed out the WLP as the most ancient carbon fixation pathway known (e.g.Ferry and House 2005;Fuchs 2011;Martin and Sousa 2016;Weiss et al. 2016;Camprubi et al. 2017).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
