Detailed explanation-1: -Cladistics (/kləˈdɪstɪks/; from Ancient Greek (kládos) ‘branch’) is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry.

Detailed explanation-2: -Cladistics refers to a biological classification system that involves the categorization of organisms based on shared traits. Organisms are typically grouped by how closely related they are and thus, cladistics can be used to trace ancestry back to shared common ancestors and the evolution of various characteristics.

Detailed explanation-3: -The method that groups organisms that share derived characters is called cladistics or phylogenetic systematics. Taxa that share many derived characters are grouped more closely together than those that do not. The relationships are shown in a branching hierarchical tree called a cladogram.

Detailed explanation-4: -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.
