Two forms of analysis are used to evaluate and interpret the Baum test. The global structure analysis sees the tree as a whole; for example, the tree's overall size and location on the paper. The internal structure, raised by Emil Jucker, focuses on the analysis of finer details of the tree. [3]
A metric tree is any tree data structure specialized to index data in metric spaces. Metric trees exploit properties of metric spaces such as the triangle inequality to make accesses to the data more efficient. Examples include the M-tree, vp-trees, cover trees, MVP trees, and BK-trees. [1]
An alignment-free bioinformatics procedure to infer distance-based phylogenetic trees from genome assemblies, specifically designed to quickly infer trees from genomes belonging to the same genus: MinHash-based pairwise genome distance, Balanced Minimum Evolution (BME), ratchet-based BME tree search, Rate of Elementary Quartets: A. Criscuolo ...

By expressing models in terms of the instantaneous rates of change we can avoid estimating a large numbers of parameters for each branch on a phylogenetic tree (or each comparison if the analysis involves many pairwise sequence comparisons). The models described on this page describe the evolution of a single site within a set of sequences.
Today, trees and other plants are at the mercy of animals, and so have need of an advocate like the Lorax. In the. In the 2012 computer animated movie The Lorax (based on the Dr. Seuss book of the ...
Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses.The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species.
The "minimum evolution problem" (MEP), in which a minimum-summed-length phylogeny is derived from a set of sequences under the ME criterion, is said to be NP-hard. [13] [14] The "balanced minimum evolution problem" (BMEP), which uses the newer BME criterion, is APX-hard. [5] A number of exact algorithms solving BMEP have been described.
