Figure 2. Synchronous expansion scenarios.
(a) None of n taxa synchronously expanding at one time (ψ = 1; ζ = 0.0). (b) Minority of n taxa synchronously expanding at one time (ψ = 1; ζ = 0.2-0.4). (c) Half of n taxa synchronously expanding at one time (ψ = 1; ζ = 0.5-0.6). (d) Majority of n taxa synchronously expanding at one time (ψ = 1; ζ = 0.7-0.8). (e) All of n taxa synchronously expanding at one time (ψ = 1; ζ = 1.0). (f) Half of n taxa synchronously expanding at one time, half of n taxa synchronously expanding at another time (ψ = 2; ζ1 = 0.5-0.6; ζ2 = 0.4-0.5).
