A history of coevolution increases genetic variation in the susceptibility of Drosophila to viruses, largely by introducing major-effect resistance polymorphisms into populations.

The most recent common ancestor of humans, chimpanzees, and bonobos possessed a foot adapted to terrestrial quadrupedalism and climbing.

Empathy can evolve and foster cooperation in a game-theoretic analysis of behavior.

When an individual makes a judgement about the actions of another individual, taking the latter's viewpoint into consideration enhances cooperation in society at large.

A 99-million year old beetle in amber was a myrmecophile—a social impostor of the earliest-known ant colonies—revealing the most ancient behavioral symbiosis yet discovered in the Metazoa.

Quantitative genetics approaches using Caenorhabditis elegans facilitate the discovery of a novel arsenic toxicity mechanism.

Diverse sophisticated phylogenetic analyses update the phylogeny of the Alphaproteobacteria and show that the parasitic Holosporales is a derived group within the Rhodospirillales order which comprises primarily free-living alphaproteobacteria.

Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.

Many prior signals of polygenic adaptation on human height do not replicate in the UK Biobank.

mille-pattes micropeptides have conserved function in insect embryonic patterning together with transcription factor Shaven-baby and ubiquitin ligase Ubr3, except in flies wherein restoring broad embryonic Svb expression restores patterning potency.
