A dendrogram is a diagram representing a tree. This diagrammatic representation is frequently used in different contexts: This diagrammatic representation is frequently used in different contexts: in hierarchical clustering , it illustrates the arrangement of the clusters produced by the corresponding analyses.
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
Regular phylogenetic tree – Generally called a dendrogram, it is a diagram with straight lines representing a tree. It would show a column of nodes representing individual taxa, and the remaining nodes represent the clusters to which the data belong, with the arrows representing the distance: a way to measure how different they are ...
A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be ...

Width Width in pixels of the created image; the corresponding height is calculated automatically. Predefined values: 1–28 seats, 280px; 29–100 seats, 300px; over 101 seats, 350px.
Dendrogram of various classes of endogenous retroviruses Endogenous retroviruses ( ERVs ) are endogenous viral elements in the genome that closely resemble and can be derived from retroviruses . They are abundant in the genomes of jawed vertebrates , and they comprise up to 5–8% of the human genome (lower estimates of ~1%).
