SUPERTREE Meaning and
Definition
-
A supertree is a concept in the field of biology, specifically in phylogenetics, which refers to a large-scale representation of the evolutionary relationships between different groups of organisms. It is constructed by merging the information from multiple smaller phylogenetic trees into a single, more comprehensive tree structure that encompasses a wide diversity of species.
The technique of creating a supertree involves combining the existing phylogenetic trees generated for different subsets of species, often based on different data sets or methodologies. The goal is to generate a more inclusive and accurate depiction of the evolutionary history of a particular group of organisms, such as a family, order, or even larger taxonomic categories.
Supertrees are constructed using various algorithms and mathematical techniques to reconcile the conflicts and differences among the individual trees. This process involves identifying areas of agreement and disagreement, determining which relationships are most supported by the available data, and resolving conflicts or uncertainties through careful analysis and inference.
The resulting supertree provides a broader perspective on the evolutionary relationships among the included species, offering insights into their shared ancestry, diversification patterns, and evolutionary trends. It allows researchers to study the larger patterns of evolution and diversification across different taxa, facilitating comparisons and analyses that would not be possible from studying individual phylogenies alone.
Supertrees are valuable tools in understanding the tree of life and elucidating the evolutionary history of organisms, providing a means to synthesize knowledge from various sources and reveal the interconnectedness of life on Earth.
Etymology of SUPERTREE
The word "supertree" is a formation by combining two words: "super" and "tree".
- "Super" is derived from the Latin word "super", meaning "above" or "over". It is often used as a prefix to emphasize something that is of a higher degree, quality, or size.
- "Tree" refers to the tall perennial woody plant with a single main stem or trunk, which usually branches out into smaller limbs and foliage.
When combined, "supertree" conveys the idea of a tree that is above or superior to the typical extent or qualities of a regular tree, potentially referencing a larger, more impressive, or extraordinary tree. In various scientific fields, "supertree" can also refer to a phylogenetic tree that combines smaller trees into a single tree to represent the evolutionary relationships of a group of organisms.
