For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

G-protein-coupled receptors (GPCRs) are found in a wide range of organisms and are central to a cellular signaling network that regulates many basic physiological processes. GPCRs are the focus of a ...

Ever since the genetic code was cracked, those mutations have generally been assumed to be neutral, or nearly so. But in a study published online June 8 in the journal Nature that involved the genetic ...
