Evolutionary novelty is promoted by a macroevolutionary pulse of developmental plasticity, but is enhanced by secondary fixation, which permits developmental character release and further morphological exploration.
RNA sequencing of individuals within a wild baboon population reveals extensive power to detect functional regulatory variation, and suggests that the set of genes affected by such variation may be conserved across species.

Methylation specifically enhances the ability of hopanoids to rigidify membranes under physiologically relevant conditions, which impacts the current interpretation of the 2-methylhopane fossil record.

An identical DNA base pair change has occurred in divergent sticklebacks to alter the expression of a major developmental gene controlling armor plates, thus providing a molecular link between particular enhancer changes, cell signaling, and repeated skeletal evolution in natural populations.
Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.

The analysis of the genomes of two lineages of influenza B virus (Victoria and Yamagata) reveal that their phylodynamics are fundamentally different, and are determined by a complex relationship between virus transmission, age of infection and receptor binding preference.

Quantitative system-level analysis of a pattern-forming gene regulatory network in a non-model organism shows that dynamic changes in gene expression evolve through quantitative system drift.
Loss-of-heterozygosity mutations, but not aneuploidies, are linked to the evolution of drug resistance in Candida albicans isolated from immunocompromised patients.
