Genome sequencing of mice selected for longer limbs reveals that rapid selection response is due to both discrete loci and polygenic adaptation.

Relative value perception, a basic tenant of Behavioural Economics, is demonstrated in an insect, and further shown to be driven by cognitive processes and induced by private and social information.

Robust wrinkling pattern of the frilled dragon’s spectacular erectile ruff emerges from an elastic instability during homogeneous growth of the embryonic neck fold frustrated by its attachment to adjacent tissues.

Genomic polymorphism across centromeric regions of humans is organized into large-scale haplotypes with great diversity, including entire Neanderthal centromeres.

The spectacular frill around the neck of the lizard Chlamydosaurus has its origins in a mechanical instability that arises during development.

Cuttlefish embryos reveal that cephalopod mollusks evolved specialized arms and tentacles by activating the same genetic circuits that control development of limbs in arthropods and vertebrates.

The same genes and signaling pathways control the formation of limbs in vertebrates, arthropods and cuttlefish.

Beewolf wasp eggs release nitrogen oxides to provide protection against fungi and other microbes.

To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.
