WebBayesian methods are increasingly being used to estimate divergence times without the restrictive assumption of a global clock. Little is known about their reliability for shallow phylogenies where DNA sequence divergence is low. We analyzed both simulated and real sequences to evaluate dating methods in phylogenies with mid-late Miocene roots. WebPart One introduces molecular dating approaches and time calibration ideas that allow for the determination of evolutionary timescales of microbial lineages. Part Two describes …
