Estimated F _ST from simulation. The estimated F _ST from two populations simulated to have diverged over 0, 10, 20, and 50 thousand generations, as a function of the underlying coalescent process. Dashed lines show the relationship between the F _ST value estimated from mtDNA data and the estimated number of generations since divergence, for the different coalescent processes for the five marine invertebrate species, Cellana ornata, C. radians, C. flava (Goldstien et al. [16]), Coscinasterias muricata (Perrin et al. [34]), and Patiriella regularis (Waters and Roy [44])
