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 into the proteins of thermophiles/hyperthermophiles) allows inferences to be made on the mesophilic or thermophilic natu

Galtier et al. (Science 1999, 283, 220}221) exploit the correlation between the optimal growth temperature in prokaryotes and the G#C content of rRNAs and establish that the last universal common ancestor (LUCA) lived in a mesophilic environment. This result was achieved by estimating the G#C conten

The coevolution theory of genetic code origin (Wong, J. T. 1975, Proc. Natl Acad. Sci. ;.S.A. 72, 1909}1912) is assumed here to be substantially correct. This theory is based on the strict parallelism of the biosynthetic relationships between amino acids and the organization of the genetic code and
