Different colors show the mutations and the animals infected, helping scientists predict which mutations might make the virus an efficient transmitter to human beings.
Anyone with the more recent incarnations of Google software can access the video of the avian flu map, but would need extra knowledge to understand the details, said Andrew Hill, a University of Colorado at Boulder graduate student and co-author of a study about the map that appears in the current issue of Systematic Biology.
