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 ...
A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...
ANN ARBOR—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 ...
What happens to the thousands of intestinal cells that have tumour-initiating DNA mutations? A study in mouse models shows that most are eliminated by strong negative selection, but those that survive ...
Clones grown from embryo plants in culture. A UC Davis study shows that clones grown in this way can have 35 times as many mutations in their DNA as plants propagated from cuttings and grown in a ...
