—Ancestral state reconstruction of genome size (in kilobases, kb) in the palms under (A) Brownian Motion, where “3.6 Gb” is the ancestral estimate for the palms and (B) genome size under an Ornstein–Uhlenbeck model. Asterisks next to species names indicate a different species of the same genus was sampled in the phylogenetic tree; asterisks next to branches in (B) represent significant trait shifts (n = 4 shifts, BIC = 991.3; Pagel’s λ =  7.8 × 10⁻⁵, P = 1.0; Blomberg’s K = 0.47, P = 0.60).
