During the 19th and early 20th centuries, ideas related to the possible origin in space of bioorganic molecules, or seeds, or even germs and organisms (and how they reached the Earth) included the Panspermia theory. Based on the idea of the eternity of life proposed by eminent physicists – such as Arrhenius and Kelvin – ‘Panspermia’ is mainly divided into two branches: lithopanspermia (transport of germs inside stones traveling in space) and radiopanspermia (transport of spores by radiative… 
On the applicability of Darwinian principles to chemical evolution that led to life
TLDR
A gradual transition from a complex pre-life system to a mixture of complex chemical cycles that reproduce and secure energy is envisaged, which is called the transition zone and may or may not lead to life.
A study of the actin-like MamK from Magnetospirillum gryphiswaldense MSR-1 and its role in magnetosome organisation
TLDR
In vitro characterisation of recombinant Magnetospirillum gryphiswaldense MSR-1 MamK shows the formation of large two-dimensional sheets, which are consistent with in vivo microscopic studies of MamK where polymerisation has been observed.
Review Early assembly of cellular life
TLDR
Information on early bacterial life on Earth is examined using information from several disciplines using physics, thermodynamics, planetary sciences, geology, biogeochemistry, lipid chemistry, primordial cell structures, cell and molecular biology, microbiology, metabolism and genetics.

Resistance of Microorganisms to Extreme Environmental Conditions and Its Contribution to Astrobiology
TLDR
The present work examines the recent discoveries and the principal advances concerning the resistance of microorganisms to extreme environmental conditions, and analyzes its contributions to the development of the main themes of astrobiology: the origins of life, the search for extraterrestrial life, and the dispersion of life in the Universe.
The search for alien life in our solar system: strategies and priorities.
TLDR
It is judged that an intensive investigation of a small number of bodies in the authors' Solar System is more likely to succeed than a broad-based survey of a great number of worlds.
ON THE IMPORTANCE OF SETI FOR TRANSHUMANISM
It is argued that astrobiology in general, and the search for extraterrestrial intelligence in particular, are of foremost importance for the transhumanist endeavor. It is sketched how one can show
Biological evidence against the panspermia theory.

TLDR
Onboard of several spacecrafts, spores of Bacillus subtilis were exposed to selected parameters of space, such as space vacuum, different spectral ranges of solar UV-radiation and cosmic rays, applied separately or in combination, and their survival and genetic changes after retrieval are studied.
A production of amino acids under possible primitive earth conditions.
TLDR
In this study, an apparatus was built to circulate CHI4, NH3, H2O, and H2 past an electric discharge, and the resulting mixture has been tested for amino acids by paper chromatography.
