    Dengue genetic divergence generates within-serotype antigenic variation, but serotypes dominate evolutionary dynamics

    Sidney M Bell et al.
    Each dengue serotype contains moderate antigenic diversity, and population immunity drives clade turnover in a hyperendemic population.

    Phylogenetic divergence of cell biological features

    Michael Lynch
    Cell biological features are subject to stochastic forces of mutation and random genetic drift, which together cause lineages exposed to identical selection pressures to diverge, and mean phenotypes to deviate from expectations under optimizing selection.

    Synteny-based analyses indicate that sequence divergence is not the main source of orphan genes

    Nikolaos Vakirlis et al.
    Homology information implicit in regions of conserved synteny allows quantification of gene origination by complete sequence divergence, revealing a larger-than-expected role for other mechanisms of origin, including de novo origination.

    Natural selection and repeated patterns of molecular evolution following allopatric divergence

    Yibo Dong et al.
    The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.

    A large genomic insertion containing a duplicated follistatin gene is linked to the pea aphid male wing dimorphism

    Binshuang Li et al.
    The application of long-read sequencing to the pea aphid wing dimorphism system reveals genomic structural divergence as a genetic mechanism of adaptation.

    Genetic Novelty: How new genes are born

    Urminder Singh, Eve Syrkin Wurtele
    Analysis of yeast, fly and human genomes suggests that sequence divergence is not the main source of orphan genes.
