Prior Schemes (PS) used in BPP analyses. Prior distributions on τ represent two relative divergence depths (deep and shallow) and on θ represent two relative effective population sizes (large and small) scaling mutation rates.

PS	Effective pop. size	Divergence depth	Gamma distribution for prior
1	Large	Deep	θ = Γ [1, 10] and τ = Γ [1, 10]
2	Large	Shallow	θ = Γ [1, 10] and τ = Γ [2, 2000]
3	Small	Shallow	θ = Γ [2, 2000] and τ = Γ [2, 2000]
4	Small	Deep	θ = Γ [2, 2000] and τ = Γ [1, 10]
