| Open AccessUnfamiliarity generates costly aggression in interspecific avian dominance hierarchies
Although intraspecific dominance hierarchies are common, large scale interspecific dominance hierarchies are unknown. Using data from hundreds of avian species, the authors find that species that are more familiar with each other engage in less aggression and the aggression is resolved more directly.

| Open AccessDental morphology in Homo habilis and its implications for the evolution of early Homo
The origin of the genus Homo is debated. Here, the authors investigate the morphology of the H. habilis enamel-dentine junction using a sample of 911 hominin and extant ape teeth, finding that H. habilis has more in common with Australopithecus than later members of the genus Homo.

Slowly evolving cnidarians are useful models to study genome architecture. This study shows that sea anemones have a high degree of chromosomal macrosynteny, but poor microsynteny conservation. This is correlated with a small genome size and short distances of cis-regulatory elements to genes.

| Open AccessThe Mla system of diderm Firmicute Veillonella parvula reveals an ancestral transenvelope bridge for phospholipid trafficking
E. coli maintains membrane lipid asymmetry by transferring glycerophospholipids from the outer membrane to the inner membrane; this requires outer membrane protein MlaA, periplasmic chaperone MlaC, and inner-membrane complex MlaBDEF. Here, the authors show that in some bacteria that lack MlaA and MlaC, MlaD forms a transenvelope bridge comprising a typical inner-membrane domain and, in addition, an outer-membrane domain.
