I have a phylogenetic tree which visually has 3 major clades, one of which forks into two minor clades. I am discussing the groups in the text in regards to the metadata but I want to statistically/technically describe why the groups are seperate.
What is the best way to achieve this? The tree is UPGMA Jackknife generated, with around 150 samples. Note: These are not based on sequence similarity but community structure, so it has to be based on the tree rather than that underlying sequence or similar.
