Figure 3From: Constructing a meaningful evolutionary average at the phylogenetic center of massRepresentative points of a three-taxon tree for various weighting schemes. Solid black lines drawn as x-, y-, and z-axes show the branches of the tree that join species 1, 2, and 3 (white numbers atop black circles) to the phylogenetic root at (0,0,0). Black rectangles at coordinates (x,y,z) indicate representative points for weighting schemes ACL, BM, and VA.Back to article page
