    A novel enhancer near the Pitx1 gene influences development and evolution of pelvic appendages in vertebrates

    Abbey C Thompson et al.
    Regulatory sequences downstream of a key limb identity gene are required for normal sizes of leg bones, and are changed in wild species with dramatic alterations in pelvic structures.

    Maternally regulated gastrulation as a source of variation contributing to cavefish forebrain evolution

    Jorge Torres-Paz et al.
    Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

    Developmental hourglass and heterochronic shifts in fin and limb development

    Koh Onimaru et al.
    Omics approaches reveal conserved and diversified gene regulation between fin and limb development.

    Generation of shape complexity through tissue conflict resolution

    Alexandra B Rebocho et al.
    Genetic modulation in patterns of tissue conflict play a major role in the development and evolution of shape diversity.

    New light shed on the early evolution of limb-bone growth plate and bone marrow

    Jordi Estefa et al.
    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.

    A SoxB gene acts as an anterior gap gene and regulates posterior segment addition in a spider

    Christian Louis Bonatto Paese et al.
    Sox21b-1 regulates simultaneous formation of anterior segments and addition of posterior segments in a spider, which resembles segmentation in long- and short-germ insects, and suggests SoxB regulation of segmentation is an ancestral feature of arthropods.

    Secondary ossification center induces and protects growth plate structure

    Meng Xie et al.
    The principle underlying the appearance of the growth plate, an organ responsible for longitudinal growth, has implications for various cartilage pathologies including growth abnormalities in children, trauma and osteoarthritis.

    Epigenetic conservation at gene regulatory elements revealed by non-methylated DNA profiling in seven vertebrates

    Hannah K Long et al.
    Islands of non-methylated DNA are shown to perform a similar epigenetic role in many different vertebrate species.

    Hippo signaling determines the number of venous pole cells that originate from the anterior lateral plate mesoderm in zebrafish

    Hajime Fukui et al.
    The Hippo signaling restricts the number of SHF cardiomyocytes in the venous pole by negatively regulating Bmp-Smad signaling in the cells of lateral plate mesoderm.

    Measuring the distribution of fitness effects in somatic evolution by combining clonal dynamics with dN/dS ratios

    Marc J Williams et al.
    Measurement of the distribution of fitness effects of new mutations arising in human oesophagus and skin, via new mathematical theory linking dn/ds values and fitness coefficients.
