Shared complexities of backbone segmentation between cartilaginous fishes and tetrapods originate much earlier in vertebrate evolution than previously thought.
Isolation of a gokushovirus capable of lysogenizing enterobacteria challenges previous notions about the biology of the most prolific phages within the Microviridae and facilitates experimental study in a model organism.

The application of long-read sequencing to the pea aphid wing dimorphism system reveals genomic structural divergence as a genetic mechanism of adaptation.

The morphology of the inner ear distinguishes major anthropoid clades and enables the proposal of various shared-derived features for apes as a whole, lesser apes, and great apes and humans.

Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

Phylogenetic analyses demonstrate an evolutionary trade-off between the amount of harm inflicted by a broad host-range virus and how effectively the virus positions itself within plants to enable onward transmission.

Within 100 generations after an environmental shift in an evolution experiment, rapid sex-specific adaptation occurred, which is potentially facilitated by selection on standing variation in sex-specific genetic architecture.
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.
