Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE) have uncovered a key role of a molecular signalling pathway (the Shh pathway) in their formation. This research provides new insights into the morphogenetic mechanisms that led to feather diversification throughout evolution.
A drug-resistant type of bacteria that has adapted to health care settings evolved in the past several years to weaponize an antimicrobial genetic tool, eliminating its cousins and replacing them as the dominant strain. University of Pittsburgh School of Medicine scientists made the discovery when combing through local hospital data—and then confirmed that it was a global phenomenon.
Researchers from the German Primate Center—Leibniz Institute for Primate Research and the Max Planck Institute of Molecular Cell Biology and Genetics have discovered two specific genes that evolve exclusively in humans jointly influence the development of the cerebrum. They have thus provided evidence that these genes contribute together to the evolutionary enlargement of the brain.
Sometimes, the most significant scientific discoveries happen by accident. Scientists have long known that whole-genome duplication (WGD)—the process by which organisms copy all their genetic material—plays an important role in evolution. But understanding just how WGD arises, persists, and drives adaptation has remained poorly understood.
Genes and society shape each other. This comic, based on our Nature Human Behaviour article, shows how social inequality leaves genetic traces — and how social structures and genetics are linked across generations.
A genetic mutation in horses that would typically halt protein production has become a molecular asset. Researchers at Johns Hopkins University and Vanderbilt University have identified a rare instance of genetic recoding that enhances oxygen metabolism and energy production in horses, donkeys, and zebras.
