CLADISTICS Meaning and
Definition
-
Cladistics is a methodological approach within the field of evolutionary biology that aims to categorize and classify organisms based on their evolutionary relationships to one another. It focuses on grouping species together based on shared evolutionary characteristics, such as their specific anatomical, morphological, physiological, or genetic traits.
The fundamental principle of cladistics is the assumption that all living organisms originate from a common ancestor. This underlying idea forms the basis for constructing cladograms, which are branching diagrams that depict the evolutionary relationships between different organisms. By analyzing and comparing various traits across different species, cladistics seeks to determine which shared characteristics are derived from a common ancestor and which are independently acquired or evolved.
In cladistics, classification is based on the concept of clades, which are groups of organisms that include a common ancestor and all of its descendants. These groups are determined by identifying shared derived traits, also known as synapomorphies, that are unique to a particular clade. The more shared derived traits organisms have in common, the more closely related they are considered to be.
Cladistics provides a framework for understanding the evolutionary history and relationships of organisms, allowing researchers to infer patterns of descent and predict ancestral features. This method has revolutionized the field of biological classification, providing a more objective and scientific approach to taxonomy. By using cladistics, scientists can construct more accurate phylogenetic trees, track evolutionary changes, and gain insights into the diversity and interconnectedness of life on Earth.

Etymology of CLADISTICS
The word "cladistics" derives from the Greek word "klados", meaning "branch", and the suffix "-istics", which relates to the study or knowledge of a particular subject. Cladistics is a method of classifying organisms based on their evolutionary relationships, emphasizing the branching patterns of shared characteristics. The term was coined by the German entomologist and evolutionary biologist Willi Hennig in his book "Phylogenetic Systematics" published in 1966.
