    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.

    Molecular function limits divergent protein evolution on planetary timescales

    Mariam M Konaté et al.
    Orthologous proteins that continuously maintain the same molecular function do not usually diverge beyond a certain level of sequence and structural similarity.

    Evidence for a common evolutionary rate in metazoan transcriptional networks

    Anne-Ruxandra Carvunis et al.
    Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.

    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.

    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.

    Expansion of the circadian transcriptome in Brassica rapa and genome-wide diversification of paralog expression patterns

    Kathleen Greenham et al.
    Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.

    Inferring joint sequence-structural determinants of protein functional specificity

    Andrew F Neuwald et al.
    A statistical approach for predicting non-active site residues responsible for allostery, cooperativity, or other subtle but functionally important interactions is described and applied to various protein families.

    Uncoupling evolutionary changes in DNA sequence, transcription factor occupancy and enhancer activity

    Pierre Khoueiry et al.
    Interspecies comparison of transcription factor occupancy during embryogenesis reveals potential co-operative relationships between factors and uncovers the inherent plasticity of developmental enhancers to overcome divergence in transcription factor occupancy.

    Conservation of peripheral nervous system formation mechanisms in divergent ascidian embryos

    Joshua F Coulcher et al.
    Developmental regulatory mechanisms for peripheral nervous system formation appear to be conserved in ascidians despite extensive genomic divergence after 390 MY of separate evolution.

    Introgression of regulatory alleles and a missense coding mutation drive plumage pattern diversity in the rock pigeon

    Anna I Vickrey et al.
    Different kinds of molecular changes at one genetic locus control different feather pigmentation patterns, and the darkest patterns resulted from hybridization with another species.
