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.

Whereas partner-serving phenotype is intuitively quantified as benefit release rate, molecular genetics revealed an example where this thinking fails, motivating a more general metric.

Shorebird flocks fly in a formation that re-creates the neighbor positioning relationship of a V-formation in cluster flocks of more than 1000 birds.

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

Natural selection shaped CHC22 clathrin genetic variation in humans with different diets and potentially influenced the human insulin response.
