In a recent article, Nelson-Sathi et al.(NS) report that the origins of major archaeal lineages
(MAL) correspond to massive group-specific gene acquisitions via HGT from bacteria …

The mechanisms that underlie the origin of major prokaryotic groups are poorly understood.
In principle, the origin of both species and higher taxa among prokaryotes should entail …

Abstract Background Collections of Clusters of Orthologous Genes (COGs) provide
indispensable tools for comparative genomic analysis, evolutionary reconstruction and …

Phylogenomic analyses of archaeal genome sequences are providing windows into the
group's evolutionary past, even though most archaeal taxa lack a conventional fossil record …

Horizontal gene transfer has played an important role in shaping the evolution of bacteria,
archaea and eukaryotes, but also obscures the deep evolutionary relationships in and …

Background Haloarchaea, a major group of archaea, are able to metabolize sugars and to
live in oxygenated salty environments. Their physiology and lifestyle strongly contrast with …

Background The concept of a genomic core, defined as the set of genes ubiquitous in all
genomes of a monophyletic group, has become crucial in comparative and evolutionary …

I believe that few people would argue against that lateral gene transfer is a fundamental
process in the evolution of Bacteria and Archaea and that an understanding of this …

The origin of the eukaryotic cell is considered one of the major evolutionary transitions in the
history of life. Current evidence strongly supports a scenario of eukaryotic origin in which two …
