Branch point on phylogenetic tree

WebTree topology and branch lengths can influence estimates of phylogenetic community metrics in many ways [22,24,25,85,86], for example, underestimating phylogenetic diversity and reducing the power to detect non-random community phylogenetic structure .

WebRooted phylogenetic trees: The root of a phylogenetic tree indicates that an ancestral lineage gave rise to all organisms on the tree. A branch point indicates where lineages diverged from each other. A lineage that evolved early and remains unbranched is a basal taxon. When two lineages stem from the same branch point, they are sister taxa.
