Back in the 1970s, geneticists saw evolution as a rather conservative process. When Susumu Ohno laid out the hypothesis that most genes evolved through duplication3, he wrote that “In a strict sense, nothing in evolution is created de novo. Each new gene must have arisen from an already existing gene.” Gene duplication occurs when errors in the DNA...
Studying de novogenes turns out to be part genetics, part thought experiment. “Why is our field so difficult?” asks Anne-Ruxandra Carvunis at the University of Pittsburgh in Pennsylvania. “It is because of philosophical issues.” At its heart is a question that Carvunis has been asking for a decade: what is a gene? A gene is commonly defined as a DN...
To trace which of an organism’s genes were made de novo, researchers need comprehensive sequences for the organism and its close relatives. One crop plant that fits the bill is rice. The sweltering heat of Hainan, a tropical island in southern China, is the perfect environment for growing the crop — although the working conditions can be trying. “I...

Evolutionary genetics examines the genetic relationships among groups of organisms and how changes in their genes shape the patterns of evolution and biodiversity.
