Detailed explanation-1: -A phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors .

Detailed explanation-2: -A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.

Detailed explanation-3: -Root – The initial ancestor common to all organisms within the cladogram (incoming line shows it originates from a larger clade)

Detailed explanation-4: -A cladogram is a branching tree diagram that shows ancestral relationships among organisms. These diagrams show evolutionary relationships between different branches referred to as clades.

Detailed explanation-5: -A cladogram shows how species may be related by descent from a common ancestor. A classification of organisms on the basis of such relationships is called a phylogenetic classification. A phylogenetic classification involves placing organisms in a clade with their common ancestor.
