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

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

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.

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.

Traces of crawling locomotion, including children younger than 3 years old, are documented for the first time in the global human ichnological record.

Diversification of a conserved cholesterol binder drives functional replacement of cholesterol with symbiont-produced sterols in corals living in nutrient-poor environments.
