Special Issue Information

Dear Colleagues,

We are pleased to introduce “Feature Papers in Origins of Life”, a Life Special Issue. This Special Issue encompasses a broad range of topics related to the origins of life. We encourage submissions from both early career researchers and established researchers in the field, as our aim for this Special Issue is to publish innovative research on all aspects of the origins of life and to provide a unique perspective towards the future of the field.

All researchers are invited to contribute submissions which focus on, but are not limited to, the following foundational and emergent research topics in the origins of life and related areas:

  • Astrobiology: all topics within astrobiology, including analog environments on Earth, and the delivery of organics to Earth and other planets from space.
  • Astrochemistry: organics and prebiotic molecular precursors in molecular clouds, protoplanetary disks, and the solar nebula.
  • Planetary science: early conditions on Earth, Venus, Mars, and terrestrial exoplanets.
  • Geology, geochemistry and geobiology: early surface conditions on terrestrial-type planets.
  • Prebiotic chemistry: syntheses of monomeric and polymeric prebiotic molecules.
  • Chirality: mechanisms for the preferential selection of enantiomers of chiral molecules.
  • Chemical evolution: primitive catalysis and mechanisms for self-replication and Darwinian selection.
  • Protocells: membrane synthesis, encapsulation, and primitive ion channels.
  • Synthetic biology: non-traditional chemical systems capable of Darwinian evolution.
  • Complex systems: the chemical evolution of simple and more complex molecular precursors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Darwin’s theory of evolution by natural selection was revolutionary because it provided a mechanism by which variation could be selected. This mechanism can only operate on living systems and thus cannot be applied to the origin of life. Here, we propose a viable [...] Read more.
Darwin’s theory of evolution by natural selection was revolutionary because it provided a mechanism by which variation could be selected. This mechanism can only operate on living systems and thus cannot be applied to the origin of life. Here, we propose a viable alternative mechanism for prebiotic systems: autocatalytic selection, in which molecules catalyze reactions and processes that lead to increases in their concentration. Crucially, this provides a driver for increases in concentrations of molecules to a level that permits prebiotic metabolism. We show how this can produce high levels of amino acids, sugar phosphates, nucleotides and lipids and then lead on to polymers. Our outline is supported by a set of guidelines to support the identification of the most likely prebiotic routes. Most of the steps in this pathway are already supported by experimental results. These proposals generate a coherent and viable set of pathways that run from established Hadean geochemistry to the beginning of life. Full article
