TL;DR: The data support the theory of an autotrophic origin of life involving the Wood–Ljungdahl pathway in a hydrothermal setting and identify clostridia and methanogens, whose modern lifestyles resemble that of LUCA, as basal among their respective domains.

TL;DR: It is indicated that gene transfer from bacteria to eukaryotes is episodic, as revealed by gene distributions, and coincides with major evolutionary transitions at the origin of chloroplasts and mitochondria; and that continuous, lineage-specific lateral gene transfer, although it sometimes occurs, does not contribute to long-term gene content evolution in eukARYotic genomes.

TL;DR: To investigate the origin of higher taxa in archaea, gene distributions and gene phylogenies for the 267,568 protein-coding genes of 134 sequenced archaeal genomes are determined in the context of their homologues from 1,847 reference bacterial genomes.

TL;DR: This paper outlines an energetically feasible path from a particular inorganic setting for the origin of life to the first free-living cells, and focuses on the main evolutionary transitions in early bioenergetic evolution.

TL;DR: The data suggest that 1,089 haloarchaeal gene families that were acquired by a methanogenic recipient from eubacteria were acquired in the halo archaeal common ancestor, not in parallel in independent haloARCHaeal lineages, nor in the common ancestor of halo Archaeans and methanosarcinales.
