Superposition of the caterpillar tree family on a caterpillar-like tree family with arbitrary seed tree of size |t| ≥ 2. (A) A seed tree t and the seed tree V for the caterpillar family. (B) Superposition of V on t, so that the roots rV and rt overlap. (C) Superposition of V(2) (shaded internal nodes) on t(2) (shaded and unshaded nodes). The n = 2 caterpillar branches in V(2) and t(2) overlap, and rV still matches rt. (D) A matching coalescent history of t(2) (dashed and dotted arrows) determines a matching coalescent history of V(2) (dashed arrows) by ignoring arrows from the unshaded nodes.
