Mismatch distribution and Bayesian skyline analyses.

<p>Observed mismatch distributions (left) for clade A (above) and clade B (below) and Bayesian skylines showing the median population size through time for each clade as well as the upper and lower 95% HPD. The comparison with the expected distributions for sudden population growth (grey lines) is not significantly different for clade A (Sum of Squared Deviations = 0.0031, P = 0.08; τ = 1.45), but is significantly different for clade B (SSD = 0.0151, P = 0.01; τ = 0.14).
