THE best formula is the clock method where you imagine the backswing is a clock face.
IN my opinion the best solution is the clock method.
Recent advances in molecular phylogenetic analysis have permitted divergence dating for numerous lineages or clades through the use of molecular clock methods (Sanderson, 1997, 2002; Thorne et al.
Recent Bayesian relaxed clock methods offer a promising opportunity to account for uncertainty in phylogenies by simultaneously estimating the topology and branch lengths (Drummond et al.
Such relaxed clock methods can be classified into a number of different types, based on the assumptions they make underlying how rates evolve across the tree (for review see Welch and Bromham, 2005).
As molecular clock methods become more widely used it has become apparent that careful consideration of fossil minimum calibrations is essential.
