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.

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

During walking and turning, the fruit fly Drosophila uses variable limb coordination patterns, which exist on a low-dimensional, continuous manifold.

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.

Size control in limbs is an intrinsically determined process.

Experimental manipulation of a core DNA damage response factor and cell-cycle checkpoint regulators reveals a key role for these processes in the progenitor cells that fuel limb regeneration.

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

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

Quantitative analyses of multi-dimensional microscopy datasets with a new Fiji/ImageJ plugin for cell tracking reveal the lineage restrictions and morphogenetic cellular behaviors underlying embryonic limb outgrowth in the direct developing crustacean Parhyale hawaiensis.

A novel mechanism links mechanical signals with the molecular YAP and NOTCH signals operating during developmental myogenesis.
