The evolution of a butterfly mimetic phenotype is driven by modular cis-regulstory switches controlling a ‘hotspot’ gene.

Replicating experimental evolution from ancestral proteins shows that historical contingency steadily overwhelms chance and necessity as the primary cause of evolutionary variation in molecular sequences on long phylogenetic timescales.

More integrated brains in crown birds evolved through a mosaic assembly of new evolutionary and developmental dynamics across neuroanatomical regions that occurred along the dinosaur-bird transition.

Ornithischians, one of the three major groups of dinosaurs, developed a unique mechanism to ensure airflow in the lungs.

A new specimen of Heterodontosaurus elucidates how ornithischian dinosaurs evolved a body plan substantially different from that of other dinosaurs and what these differences meant for their breathing.

Humans showed the most widespread asymmetric connectivity between the inferior parietal lobule subregions and the rest of the brain compared to macaques and chimpanzees, which shapes hemispheric specialization in primates.

Seasonal selection is a general feature of Drosophila melanogaster genetic variation, occurring in North American and European populations and affecting large proportions of the genome.

Mathematical modeling and data analysis show that, over evolutionary times, the yeast temporal program of replication strives to avoid stalling events and minimize interference between neighbor origins.

The evolution of multidrug resistance can be most easily understood by focusing upon the dynamical equations of linkage disequilibrium.

Wild chimpanzees contrast to humans since adult male chimpanzees do not exhibit physiological indicators of biological embedding of the stress associated to maternal loss early in life.
