Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

Endoplasmic reticulum proteostasis factors enhance the mutational tolerance of influenza hemagglutinin, a model secretory pathway protein and therapeutic target, particularly improving the fitness of temperature-sensitive variants.

Early development involves both maternal and zygotic genetic effects. This dual genetic basis shapes the evolution of developmental mode in a marine annelid.

Sox21b-1 regulates simultaneous formation of anterior segments and addition of posterior segments in a spider, which resembles segmentation in long- and short-germ insects, and suggests SoxB regulation of segmentation is an ancestral feature of arthropods.

The discovery of a gene that regulates two segmentation mechanisms in spider embryos is fueling the ongoing debate about the evolution of this crucial developmental process.

Analysis of the endogenous function of deeply conserved neuropeptides in sea anemones sheds light on a primitive role of nervous systems in modulating developmental timing.

An ancient and conserved genetic mechanism for cell differentiation is under distinct negative regulation in different lineages of land plants.

The impact of changing gene expression noise on fitness reveals beneficial or deleterious effects in a stable environment depending how close the average expression level is to the fitness optimum.

Host characteristics drive the assembly of similar communities within the convergently evolved and geographically distant pitcher ecosystems of carnivorous pitcher plants.

An adaptive process of genetic homogenization in poxviruses facilitates the propagation of single nucleotide variation within gene copies and might favor the persistence of large gene copy arrays.
