In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

The incus of the middle ear plays a role in supporting the lower jaw prior to the formation of the mammalian jaw joint allowing early feeding in monotremes and marsupials.

Four species of seabird produce efficient propulsive wakes while flying in the air and while swimming underwater suggesting that selection has optimized these species for locomotion in remarkably different fluids.

Neural networks allow fast and accurate prediction of individual spatial locations from genotypes or sequencing data.

Horizontal gene transfer (HGT) helps slightly beneficial genes persist in microbial populations, incentivising cells to invest in costly DNA uptake, even in the presence of harmful selfish genetic elements.

Discovery of a novel neuropeptide signalling system in a deuterostome invertebrate reveals the evolutionary origin of prolactin-releasing peptide and its relationship with neuropeptides in protostome invertebrates.

Unique 'true' S-cone and S-cone bipolar cell distribution patterns in the mouse retina are previously unappreciated anatomical features that support enhanced short-wavelength signaling for color detection above horizon.

Transposable elements and gene amplifications can provide variation needed for novel trait refinement and adaptation to new niches, though a recalcitrant organism-environment mismatch may persist.

Adaptational tradeoffs constrain the evolutionary pathways towards antimicrobial resistance, but highly fit mutants are nevertheless likely to arise at any concentration of the drug.

Experiments in sea cucumbers reveal how the physiological responses regulated by a neuropeptide called kisspeptin have evolved.
