Testing fit of data to model is fundamentally important to any science, but publications in the field of phylogenetics rarely do this. Such analyses discard fundamental aspects of science as prescribed by Karl Popper. Indeed, not without ca...

The codon assignment of the quasi-universal genetic code can be assumed to have resulted from the evolutionary pressures that prevailed when the code was still evolving. Here, we review studies of the structure of the genetic code based on ...

The common understanding of the function of RecD, as derived predominantly from studies in Escherichia coli, is that RecD is one of three enzymes in the RecBCD double-stranded break repair DNA recombination complex. However, comparative gen...
Search for primitive Methanopyrus based on genetic distance between Val- and Ile-tRNA synthetases [0.03%]

Since evidence indicates that the Last Universal Common Ancestor (LUCA) was phylogenetically closest to Methanopyrus kandleri among living organisms with elucidated genomes, this study has been directed to a search for the most primitive Me...

We investigated the molecular evolution of duplicated color vision genes (LWS-1 and SWS2) within cyprinid fish, focusing on the most cavefish-rich genus--Sinocyclocheilus. Maximum likelihood-based codon substitution approaches were used to ...

The mitochondrial ribosomal protein S3 (rps3) gene within the fungi is extremely diverse in location and organization, some versions of this gene have been incorporated into a group I intron, others appear to have gained large insertions, m...

The following unusual tRNAs have recently been discovered in the genomes of Archaea and primitive Eukaryota: multiple-intron-containing tRNAs, which have more than one intron; split tRNAs, which are produced from two pieces of RNA transcrib...

For the RNA-world hypothesis to be ecologically feasible, selection mechanisms acting on replicator communities need to be invoked and the corresponding scenarios of molecular evolution specified. Complementing our previous models of chemic...
