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.

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.

Ancestral sequence reconstruction of an essential muscle protein involved in oxygen storage and transport accurately tracks secondary aquatic transitions in a speciose clade of insectivorous mammals.

Mutations that directly benefit both self and cooperative partner can readily evolve to promote cooperation.

The number and effects of mutations leading to full drug resistance crucially determine treatment failure probability and should be used to inform antimicrobial treatment strategies with regard to avoidance of resistance emergence.
