The employment of xenopsin in ciliary and mixed microvillar/ciliary eye sensory cells in several protostome animals suggests high evolutionary plasticity of photoreceptors.
Lateral gene transfer is unable to resist mutation accumulation in large genomes, leading to selective pressure for the origin of meiotic sex in the first eukaryotes.

This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.

The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

A comparative and experimental research refutes the controversial hypothesis that plasticity played a major role in the convergent evolution of Anolis ecomorphs.
Lizards that live in the Greater Antilles exploit a large range of skeletal variations to adapt to similar habitats, in defiance of the theory of plasticity-led evolution.
Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.
