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.

Polygenic selection signals in humans estimated from previously existing GWAS should be viewed with caution due to concerns about residual population stratification.

Great care is needed when interpreting claims about the genetic basis of human variation based on data from genome-wide association studies.

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.

Retention of genetic diversity at immune-related loci drives the pattern of genetic variation in selfing Capsella.

The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.
