Figure S33 (right).'esults of ASTRAL's polytomy test based on the 821 single-copy gene trees mapped onto the single-copy genes ASTRAL species tree (Figure S14). Node numbers are tests of the null hypothesis that a branch should be replaced by a polytomy. Only node numbers> 0.05 are shown. Branch lengths are set equal for easier visualisation.
