When reading a phylogenetic tree, which of the following is true regarding the evolutionary relationships among the taxa represented on the tree? Taxa located at adjacent tips of the branches are always more closely related to each other than to other taxa on the tree. Therefore, a species is always equally related to the taxon on the branch immediately to the right it and the taxon on the branch immediately to the left of it The branch lengths always represent the amount of morphological change between taxa The internal nodes (branching points) of the tree represent the most recent common ancestors of the taxa connected by the branches The position of taxa on the tree is completely arbitrary and does not reflect their evolutionary relationships

Question
When reading a phylogenetic tree, which of the following is true regarding the evolutionary
relationships among the taxa represented on the tree?
Taxa located at adjacent tips of the branches are always more closely related to each other than to other taxa
on the tree. Therefore, a species is always equally related to the taxon on the branch immediately to the right
it and the taxon on the branch immediately to the left of it
The branch lengths always represent the amount of morphological change between taxa
The internal nodes (branching points) of the tree represent the most recent common ancestors of the taxa
connected by the branches
The position of taxa on the tree is completely arbitrary and does not reflect their evolutionary relationships
