A new machine learning technique helps detect beneficial mutations in population genetic datasets. (brownmedicinemagazine.org)
Otherwise beneficial mutations compete with each other so that no one mutation is selected over another. (sciencedaily.com)
In this way, natural selection can create the astonishing organisms we see around us, the result of countless trillions of beneficial mutations slowly assembled over billions of years (see Mutations can only destroy information). (newscientist.com)
