Distinct ossification trade-offs illuminate the shoulder girdle reconfiguration at the water-to-land transition.

This study identifies Gli3's role in regulating ossification pathways in zebrafish pectoral girdles, revealing developmental trade-offs that may explain the evolution of tetrapod-like structures.

Axial regionalization in Tiktaalik roseae and the origin of quadrupedal locomotion

This study analyzes the axial skeleton of Tiktaalik roseae to show regionalization and sacral ribs, suggesting early evolution of features supporting quadrupedal locomotion before limb development.

The coevolution of mammae number and litter size

This study analyzes 2,301 mammal species to show how mammae number and litter size coevolve, finding that mammae number approximates maximum litter size and explains more variation in litter size than other traits.

Multiscale activity imaging in the mammary gland reveals how oxytocin enables lactation

The paper uses multiscale imaging to show how oxytocin-driven Ca2+ oscillations in mammary epithelial cells coordinate milk ejection through synchronized contractions.

Mammary mechanobiology: mechanically-activated ion channels in lactation and involution

This study investigates mechanical forces in mammary glands during lactation and involution, highlighting the role of PIEZO1 in force sensing and its physiological importance.

Evidence against tetrapod-wide digit identities and for a limited frame shift in bird wings

The paper challenges the conservation of digit identities across tetrapods and suggests a limited frame shift in bird wings based on gene expression patterns.
