Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.

The principle underlying the appearance of the growth plate, an organ responsible for longitudinal growth, has implications for various cartilage pathologies including growth abnormalities in children, trauma and osteoarthritis.

A broad mutational target is the cause of the high mutational variance and corresponding fast phenotypic evolutionary rate in P3.p cell fate in Caenorhabditis nematodes.

The speed at which a cell fate decision in nematode worms evolves is due to the number of genes that control the decision, rather than to a high mutation rate.

The combination of phenotypic measures of antigenic drift and genotypic measures of functional constraint improves the accuracy of long-term seasonal influenza A/H3N2 forecasts.

New measures of influenza virus fitness could improve vaccine strain selection through more accurate forecasts of the evolution of the virus.

Advanced orthology clustering of bilaterian and non-bilaterian sequences identifies 157 bilaterian-specific genes which are linked to key morphological features of this animal group.

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.
