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.

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.
