    Reverse evolution leads to genotypic incompatibility despite functional and active site convergence

    Miriam Kaltenbach et al.
    Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.

    Convergent Evolution: Shaping the import system of mitochondria

    Kostas Tokatlidis
    Evidence is accumulating that unrelated species have independently evolved the same way of importing proteins in their mitochondria.

    Convergence of topological domain boundaries, insulators, and polytene interbands revealed by high-resolution mapping of chromatin contacts in the early Drosophila melanogaster embryo

    Michael R Stadler et al.
    Fruit fly chromosomes are divided into discrete structural domains by regions of decompacted chromatin, suggesting a novel model for the formation of a known class of genetic elements.

    Subterranean mammals show convergent regression in ocular genes and enhancers, along with adaptation to tunneling

    Raghavendran Partha et al.
    Repeated evolution of eye regression in subterranean mammals helps identify genes and regulatory elements involved in visual perception and development of the eye, and predicts candidate sequences with a potential role in ocular disorders.

    A cerebellar substrate for cognition evolved multiple times independently in mammals

    Jeroen B Smaers et al.
    Multiple independent directional selection events on a neural substrate that underpins domain-general associative abilities partly explains independent occurrences of complex behavior in different lineages of mammals.

    Phenotypic landscape inference reveals multiple evolutionary paths to C4 photosynthesis

    Ben P Williams et al.
    Computational modelling indicates that C4 photosynthesis in distantly related plant species arose through a number of independent evolutionary paths.

    An insect-like mushroom body in a crustacean brain

    Gabriella Hannah Wolff et al.
    An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

    An atomic-resolution view of neofunctionalization in the evolution of apicomplexan lactate dehydrogenases

    Jeffrey I Boucher et al.
    The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

    Independent evolution of functionally exchangeable mitochondrial outer membrane import complexes

    Daniela G Vitali et al.
    The convergent evolution of yeast Mim1/2 and trypanosomal pATOM36 enable the first demonstration of reciprocal functional rescue of two evolutionary unrelated mitochondrial biogenesis complexes belonging to two different eukaryotic supergroups.
