CLADOGRAM Meaning and
Definition
-
A cladogram is a branching diagram used in the field of biology to represent the evolutionary relationships among various organisms. It is a visual tool that displays the phylogenetic relationship between different species or groups of organisms based on shared characteristics or traits. Cladograms are commonly used in evolutionary biology, systematics, and taxonomy.
This diagram is constructed by identifying and comparing specific features or traits of organisms and then organizing them into hierarchical groups or clades. The branches of the cladogram represent the points at which different groups of organisms diverged from a common ancestor, with each branch point called a node. The closer the branches are to each other on the diagram, the more closely related the organisms are believed to be.
Cladograms are created using data obtained from various sources, including morphological characteristics, DNA sequences, or other genetic information. The shared features between different organisms are called derived characteristics or synapomorphies, which are traits that evolved in a common ancestor and have been passed down to its descendants. These shared derived characteristics help to determine the evolutionary relationships and the order in which the branches diverged on the cladogram.
Overall, cladograms provide a visual representation of the evolutionary history of organisms, allowing researchers to study, understand, and classify different species based on their genetic and morphological similarities and differences.

Etymology of CLADOGRAM
The word "cladogram" is derived from two Greek terms: "klados" (κλάδος), meaning "branch", and "gramma" (γράμμα), meaning "drawing" or "representation". Therefore, the term "cladogram" essentially translates to "branch drawing" or "branch representation", which accurately describes its purpose as a diagrammatic representation of evolutionary relationships between species or organisms.
