A high-temperature origin of life has been proposed, largely for the reason that the
hyperthermophiles are claimed to be the last common ancestor of modern organisms. Even …

We revisit the case for the hyperthermophilic scenario for the origin of life and the last
common ancestor. Evidence includes studies of phylogenetic trees, rRNA, G and C content …

The discovery that life flourishes on Earth at temperatures up to 110 C and that most
hyperthermophiles belong to the domain Archaea has prompted speculations about the hot …

The definition of the node of the last universal common ancestor (LUCA) is justified in a
topology of the unrooted universal tree. This definition allows previous analyses based on …

The existence of a correlation between the optimal growth temperature of various organisms
and a thermophily index (based on the propensity of amino acids to enter more frequently …

All thermophiles discovered so far are prokaryotes (Bacteria or Archaea). Furthermore,
reconstructions of rRNA phylogenies suggest that the progenitor of all prokaryotes was a …

High-temperature origin-of-life theories require that the components of the first genetic
material are stable. We therefore have measured the half-lives for the decomposition of the …

Thermodynamic data and known paleogeological data were used to deduce when and what
elements (compounds) were readily available during the whole history of the earth. On the …

Hyperthermophiles, growing optimally at 80° C and above were first discovered in 1981.
They represent the upper temperature border of life and are found within water-containing …

All reactions are accelerated by an increase in temperature, but the magnitude of that effect
on very slow reactions does not seem to have been fully appreciated. The hydrolysis of …
