Biologists have discovered evidence for a new path of evolution, and with it a deeper understanding of how quickly organisms such as viruses can adapt to their environment. The researchers say their findings, which address longstanding mysteries of how genes acquire new functions and how mutations arise to ease transmission from one host to another, could be applied to investigations of viral diseases such as Zika, Ebola and bird flu.
