Genealogy of scaly reptiles rewritten by new research

The most comprehensive analysis ever performed of the genetic relationships among all the major groups of snakes, lizards and other scaly reptiles has resulted in a radical reorganization of the family tree of these animals, requiring new names for many of the tree's new branches. The research, reported in the current issue of the journal C.R. Biologies, was performed by two biologists working at Penn State: S. Blair Hedges, professor of biology, and Nicolas Vidal, a postdoctoral fellow in Hedges' research group at the time of the research who now is a curator at the National Museum in Paris.
