Webb28 feb. 2024 · Relatedness in a phylogenetic tree is determined by descent from a recent common ancestor. When interpreting a phylogenetic tree, there is a tendency to presume that distance between taxa can be used to determine relatedness. However, branch tip proximity is positioned arbitrarily and can not be used to determine relatedness. WebbA phylogeny, or evolutionary tree, represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa (singular: taxon). The tips of the tree represent groups of descendent taxa (often species) and the nodes on the tree represent the common ancestors of those descendants. high spirits cast listWebbPhylogenetic trees are hypotheses which help to understand common ancestry.
