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.

A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.

Omics approaches reveal conserved and diversified gene regulation between fin and limb development.

A shift in antero-posterior positional information may contribute to the fin-to-limb transformation.

General principles of the limb segment control for terrestrial locomotion have emerged in evolution and highlight the existence of the laws of biological motion that apply to various animal species.

The antibody accessibility of the leptospiral surface protein, LigB, provides a guide for the rational design of improved recombinant chimeric vaccine antigens displayed on a single domain scaffold.

Despite their extreme morphologies, snakes display a global regulatory strategy of their Hox genes similar to that implemented by mammals with, however, important modifications in enhancer specificity.

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

Elucidation of the molecular basis of early wound epidermis dependence during salamander limb regeneration reveals midkine as a key modulator of wound epidermis development and wound-healing resolution.

While movement of Fgf-signaling to the limb mesenchyme accompanied a shift in function, the ultimate outcome remains a convergent tetrapod limb phenotype.
