Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo – the heron or the sparrow?
These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique developed by researchers at the University of Illinois and the University of Texas at Austin can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
An international effort involving more than 100 researchers, nine supercomputers and about 400 years of CPU time has yielded the most reliable avian tree of life yet produced, researchers report in the journal Science. The tree reflects the evolutionary relationships of 48 species of birds.
