Detailed explanation-1: -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-2: -A phylogenetic tree is an estimate of the relationships among taxa (or sequences) and their hypothetical common ancestors (Nei and Kumar 2000; Felsenstein 2004; Hall 2011). Today most phylogenetic trees are built from molecular data: DNA or protein sequences.

Detailed explanation-3: -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-4: -Phylogenetic trees are diagrams of evolutionary relationships among organisms. Scientists can estimate these relationships by studying the organisms’ DNA sequences. As the organisms evolve and diverge, their DNA sequences accumulate mutations.
