August 7, 2017—Hundreds of thousands of years ago, the ancestors of modern humans diverged from an archaic lineage that gave rise to Neanderthals and Denisovans. Yet the evolutionary relationships between these groups remain unclear. A University of Utah-led team developed a new method for analyzing DNA sequence data to reconstruct the early history of the […]

SALT LAKE CITY – Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. In some instances it might be more appropriate to call it an overhaul. Over the past 100 million years, the human lineage has lost one-fifth of its DNA, while an even greater […]

Many mammals and birds are remarkable athletes; mice work hard to dig burrows for protection and sparrows fight gravity with each flap of their wings. In order to have the energy to sustain vigorous exercise, the body’s tissues need a steady supply of oxygen, and red blood cells (RBCs) are the center of the oxygen […]
