The divergence times in millions of years ago (Mya) are shown based on multigene and multiprotein studies (Hedges and Kumar,2002; Hedges,2002; Ureta-Vidal et al.,2003). Branch lengths are not proportional to time.Download figure to PowerPoint Image published in: Wheeler GN and Brändli AW (2009) Copyright © 2009.
