A dendrogram of the Tree of Life. This phylogenetic tree is adapted from Woese et al. rRNA analysis. [3] The vertical line at bottom represents the last universal common ancestor (LUCA). Heatmap of RNA-Seq data showing two dendrograms in the left and top margins. A dendrogram is a diagram representing a tree. This diagrammatic representation is ...
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 ...
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).

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 ...
UPGMA (unweighted pair group method with arithmetic mean) is a simple agglomerative (bottom-up) hierarchical clustering method. It also has a weighted variant, WPGMA, and they are generally attributed to Sokal and Michener.
These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The points inside a curve labelled S represent elements of the set S, while points outside the boundary represent elements not in the set S.
Complete-linkage clustering is one of several methods of agglomerative hierarchical clustering.At the beginning of the process, each element is in a cluster of its own. The clusters are then sequentially combined into larger clusters until all elements end up being in the same clus
