Brian M. Wiegmann, a professor at North Carolina State University, and collaborators across the globe have mapped the evolutionary history of flies in a project that has been dubbed the "fly tree of life". The project provides a comprehensive picture of fly-life over 260 million years, plugging many evolutionary gaps. The tree -- which comprises of more than 152,000 named species -- should be able to help scientists to find out why some characteristics, for example blood feeding, have popped up over and over again across millions of years of evolution.
