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: -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. Organisms are arranged in such a way that each clade shares common traits or characteristics not shared with other clades.

Detailed explanation-4: -A cladogram is an evolutionary tree that diagrams the ancestral relationships among organisms. In the past, cladograms were drawn based on similarities in phenotypes or physical traits among organisms. Today, similarities in DNA sequences among organisms can also be used to draw cladograms.

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.
