The first complete 3D reconstruction of the compound eye of a minute wasp species sheds light on the nuts and bolts of size reduction.

Template switching during DNA replication is a frequent source of adaptive gene amplification.

The production of a single-cell atlas for developing syngnathid fish permits study of their unique traits.

An eco-evolutionary model shows that heterozygote advantage can maintain over 100 major histocompatibility complex alleles, providing a potent explanation for extraordinary immune gene diversity and challenges previous models that predicted limited allele coexistence.

Diverse histories of viral exposure, for example in individuals of different age, makes viral evolution less predictable with features of adaptive and neutral evolution.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

Mutagenizing sequences enriched with promoter motifs creates gene expression de novo, and helps to understand promoter logic, regulatory evolution, and the birth of de novo genes.

A new method to infer the spatial history of genetic ancestors from a sequence of trees along a recombining genome.

Aphid and mildew read counts leftover from the sequencing of greenhouse plants correlated with the environment of origin of the plants, and allowed the mapping of pathogen resistance genes.
