Extended Data Fig. 8: PGLS models of ln(body mass) on ln(brain mass) based on the different consensus trees.

a, Dembo et al.17 hypothesis, b, Au. sediba hypothesis, c, H. naledi hypothesis and d, H. floresiensis hypothesis. We used a generalised least-squares fit by restricted maximum likelihood (REML), and a Brownian motion correlation structure. The resulting equations and R2 are in the plots next to the regression line in red.
