How and where did life on Earth originate? To date, various environments have been
proposed as plausible sites for the origin of life. However, discussions have focused on a …

The genetic code is nearly universal, and the arrangement of the codons in the standard
codon table is highly nonrandom. The three main concepts on the origin and evolution of the …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

There are three groups of scientists dominating the search for the origin of life: the organic
chemists (the Soup), the molecular biologists (RNA world), and the inorganic chemists …

Considering the state-of-the-art views of the geochemical conditions of the primitive earth, it
seems most likely that peptides were produced ahead of all other oligomer precursors of …

The coevolution theory of the genetic code, which postulates that prebiotic synthesis was an
inadequate source of all twenty protein amino acids, and therefore some of them had to be …

Most models of the primitive atmosphere around the time life originated suggest that the
atmosphere was dominated by carbon dioxide, largely based on the notion that the …

The incorporation of orthophosphate from scarce geochemical sources into the organic
compounds essential for life under mild conditions is a fundamental challenge for prebiotic …

The adsorption of amino acids on minerals and their condensation under conditions that
resemble those of prebiotic earth is a well studied subject. However, which amino acids …

Life most likely started during the Hadean Eon; however, the environmental conditions
which contributed to the complexity of its chemistry are poorly known. A better understanding …
