Two different marsupial species display a sex-related hand preference in the opposite direction to that of placental mammals and with a stronger tendency when in an upright posture, a trait only previously known in primates.
E. coli can develop resistance to the antibiotic rifampicin, even in the absence of the drug, if grown in a thermally stressed environment, suggesting that antibiotic resistance is not always costly for bacteria to maintain.
New software that can simulate gene trees under a multispecies coalescent model with migration between subspecies shows that although inference of species tree topologies can be robust to gene flow, even detecting the presence of migration is difficult.
Phylogenetic analysis of a single opsin gene in birds shows that their vision has shifted between the visible spectrum and UV-sensitive vision at least 14 times, each of which can be explained by a single nucleotide change.
Re-evaluation of the phylogeny of the Cnidaria, using an expanded dataset of mitochondrial protein genes, differs from existing phylogeny and groups the Octocorallia and Medusozoa, resulting in a paraphyletic Anthozoa.

BMC Evolutionary Biology 2013, 13:96
BMC Evolutionary Biology is an open access, peer-reviewed journal that considers articles on all aspects of molecular and non-molecular evolution of all organisms, as well as phylogenetics and palaeontology.
It is journal policy to publish work deemed by peer reviewers to be a coherent and sound addition to scientific knowledge and to put less emphasis on interest levels, provided that the research constitutes a useful contribution to the field.
Peerage of Science
BMC Evolutionary Biology supports Peerage of Science, a new initiative to provide more recognition for reviewers and to expedite the reviewing process through shared and fair reports. BMC Evolutionary Biology welcomes manuscripts that have been reviewed through Peerage of Science and so please do indicate on your cover letter if your manuscript has already been reviewed here.
