Many-to-one function of cat-like mandibles highlights a continuum of sabre-tooth adaptations | Proceedings of the Royal Society B: Biological Sciences

Cat-like carnivorans are a textbook example of convergent evolution, with distinct morphological differences between taxa with short or elongated upper canines, the latter often being interpreted as an adaptation to bite at large angles and subdue large ...

Mammalian forelimb evolution is driven by uneven proximal-to-distal morphological diversity

Expansion of ventral foregut is linked to changes in the enhancer landscape for organ-specific differentiation - Nature Cell Biology

Wong et al. report that expanding human embryonic stem cell-derived endodermal progenitors serve as a ventral foregut model, through which they identify a link between progenitor expansion and tissue-specific changes in the enhancer landscape.
