Fig. 2. Snapshots of cluster distributions.

Distributions are shown for low (left column) and high (right column) β-values after 10⁷ generations, for 2-dimensional (top row) and 3-dimensional (bottom row) phenotype spaces. A 16 species for β = 1, λ = 1.2, σ_α = 0.5; B 47 species for β = 45, λ = 1.2, σ_α = 0.5; C 8 species for β = 1, λ = 1.2, σ_α = 0.75; D 20 species for β = 55, λ = 1.2, σ_α = 0.75. The videos of various diversification scenarios corresponding to Fig. 2 can be found here: figshare.com/s/f2d8ecf480fa372319e1. In the top row panels and corresponding videos (2-dimensional case), all phenotypes present in the evolving community are shown (represented as dots). In the bottom row panels and corresponding videos (3-dimensional case), species resulting from clustering of populations of similar phenotypes using a merging distance of Δx_species = 10⁻¹ (see second section of Methods) are represented by circles whose size is proportional to a species' population size.
