The Major Histocompatibility Complex region evolves via gene birth-and-death, resulting in short-lived genes, rapidly expanding gene subfamilies, and many gene fragments.

A comparative analysis of genome-wide seasonal gene expression dynamics across four forest tree species revealed that a shared 'molecular calendar' emerges in winter, constraining gene expression evolution and potentially limiting temporal niche partitioning and species divergence in seasonal environments.

HoxB-dependent anterior–posterior patterning and the evolutionary origin of pectoral fins.

Fitness constraints on the HIV envelope protein are highly similar in humans and rhesus macaques, emphasizing the utility of macaque models of infection and antibody development.

Ecological interactions exert contrasting evolutionary pressures on sympatric Morpho butterflies, promoting convergence in iridescence but divergence in chemical cues, illustrating how ecological interactions mediate trait evolution and sister-species coexistence.

A complementary sex determination locus is conserved in ants and dates back to approximately 112 million years ago.
