Web28. nov 2016. · Types of Phylogenetic Tree Rooted Tree: • Make inferences about the most common ancestor of the leaves or branches of the tree. • Most commonly the root is referred to as an “outgroup”. Unrooted Tree: • Make an illustration about the leaves or branches, • but not make assumption regarding a common ancestor. 9. An evolutionary grade is a group of species united by morphological or physiological traits, that has given rise to another group that has major differences from the ancestral condition, and is thus not considered part of the ancestral group, while still having enough similarities that we can group them under the same clade. The ancestral group will not be phylogenetically complete (i.e. will not form a clade), so will represent a paraphyletic taxon.
