(a) Posterior distributions of the probabilities (x-axis) of an ancestral state being matrilocal (grey bars) or patrilocal (white bars) for the four high-level subgroups corresponding in figure 3 ((i) PAN, (ii) PMP, (iii) CEMP, (iv) POc). Values given are the mean±s.d. for the distribution. Bars represent the 95% highest posterior density. (b) Posterior distribution of transition rates showing that transitions from matrilocality to patrilocality (qMP, grey bars) take values twice as high as the reverse (qPM, white bars).
