    Phylogenomic analysis supports the ancestral presence of LPS-outer membranes in the Firmicutes

    Luisa CS Antunes et al.
    Phylogenomics provides support for the Gram-positive type of bacterial cell envelope being a derived character that arose independently multiple times through loss of an ancestral outer membrane.

    Coupling adaptive molecular evolution to phylodynamics using fitness-dependent birth-death models

    David A Rasmussen, Tanja Stadler
    A new model describes how adaptive molecular evolution shapes phylogenetic trees and can be used to estimate the fitness effects of mutations from phylogenies.

    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    Meiotic Recombination: Birth and death of a protein

    Julie Clément, Bernard de Massy
    The ways in which recombination sites are determined during meiosis are becoming clearer following a phylogenomic analysis for 225 different species.

    Relief of autoinhibition by conformational switch explains enzyme activation by a catalytically dead paralog

    Oleg A Volkov et al.
    A catalytically dead paralog activates its cognate enzyme through an allosteric mechanism that combined structural and phylogenomic analysis indicates arose through acquisition of a dimerization domain, suggesting a general model for how complex allostery evolves.

    The Natural History of Model Organisms: Insights into the evolution of social systems and species from baboon studies

    Julia Fischer et al.
    Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.
