    Wnt/β-catenin signaling is an evolutionarily conserved determinant of chordate dorsal organizer

    Iryna Kozmikova, Zbynek Kozmik
    Wnt/beta-catenin signaling is essential for the specification of dorsal cell fate in amphioxus, suggesting a common evolutionary origin for the formation of the dorsal organizer in chordates.

    The yeast mating-type switching endonuclease HO is a domesticated member of an unorthodox homing genetic element family

    Aisling Y Coughlan et al.
    A family of homing genetic elements that look like inteins but work differently is the progenitor of the endonuclease that enables Saccharomyces cerevisiae to change its mating type.

    Homing Genetic Elements: Mobile DNAs and switching mating types in yeast

    Laura N Rusche
    The gene that allows budding yeast cells to switch their mating type evolved from a newly discovered family of genes named weird HO.

    Existence and functions of a kisspeptin neuropeptide signaling system in a non-chordate deuterostome species

    Tianming Wang et al.
    Identification and functional characterization of the first non-chordate kisspeptin neuropeptide system in the sea cucumber indicates the ancient origin of the intracellular signaling and physiological functions of this molecular system.

    Evolutionary expansion of apical extracellular matrix is required for the elongation of cells in a novel structure

    Sarah Jacquelyn Smith et al.
    A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.

    Retrocopying expands the functional repertoire of APOBEC3 antiviral proteins in primates

    Lei Yang et al.
    Genomes take advantage of the gene-duplicating ability of retroelements to birth novel innate immune defense genes.

    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Convergent evolution of small molecule pheromones in Pristionchus nematodes

    Chuanfu Dong et al.
    Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.
