General principles of the limb segment control for terrestrial locomotion have emerged in evolution and highlight the existence of the laws of biological motion that apply to various animal species.
Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.
A specialized conduction pathway for the electrical impulse in the heart, previously thought to be associated with the endothermic mammals and birds only, is also present in the ectothermic crocodiles.
Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.
Auditory experience of a species-specific courtship song in developing Drosophila tunes adult song perception and resultant sexual behavior more selective.
Vertebrate superfast muscles employ similar excitation–contraction strategies but distinct myosin heavy chain genes to allow superfast performance, revealing a maximum speed that cannot be overcome without sacrificing neural control.
Profiling of fibroblasts across mammals captures differences in longevity at the level of global gene expression and metabolite levels and reveals pathways that define these differences.
