Geneticists have found a mechanism sought for more than four decades that explains how gene duplication leads to novel functions in individuals. Gene duplication is a biological phenomenon that leads to the sudden emergence of new genetic material. 'Sister' genes – the products of gene duplication – can survive across long evolutionary timescales, and allow organisms to tolerate otherwise lethal mutations. read more
