2. Phylogenetic tree - Wikipedia

   en.wikipedia.org/wiki/Phylogenetic_tree

   A phylogenetic tree, phylogeny or evolutionary tree is a graphical representation which shows the evolutionary history between a set of species or taxa during a specific time. [ 1 ] [ 2 ] In other words, it is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon ...

3. Phylo (video game) - Wikipedia

   en.wikipedia.org/wiki/Phylo_(video_game)

   Developed by the McGill Centre for Bioinformatics, it was originally released as a free Flash game in November 2010. Designed as a game with a purpose, players solve pattern-matching puzzles that represent nucleotide sequences of different phylogenetic taxa to optimize alignments over a computer algorithm. By aligning together each nucleotide ...

4. Phylogenetic signal - Wikipedia

   en.wikipedia.org/wiki/Phylogenetic_signal

   Phylogenetic signal is usually described as the tendency of related biological species to resemble each other more than any other species that is randomly picked from the same phylogenetic tree. [ 1 ] [ 2 ] In other words, phylogenetic signal can be defined as the statistical dependence among species' trait values that is a consequence of their ...

6. Outgroup (cladistics) - Wikipedia

   en.wikipedia.org/wiki/Outgroup_(cladistics)

   A simple cladogram showing the evolutionary relationships between four species: A, B, C, and D. Here, Species A is the outgroup, and Species B, C, and D form the ingroup. In cladistics or phylogenetics, an outgroup [1] is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study ...

7. Tree of life (biology) - Wikipedia

   en.wikipedia.org/wiki/Tree_of_life_(biology)

   [15] Darwin's tree is not a tree of life, but rather a small portion created to show the principle of evolution. Because it shows relationships (phylogeny) and time (generations), it is a timetree. In contrast, Ernst Haeckel illustrated a phylogenetic tree (branching only) in 1866, not scaled to time, and of real species and higher taxa. In his ...

8. Sister group - Wikipedia

   en.wikipedia.org/wiki/Sister_group

   The term sister group is used in phylogenetic analysis, however, only groups identified in the analysis are labeled as "sister groups".. An example is birds, whose commonly cited living sister group is the crocodiles, but that is true only when discussing extant organisms; [3] [4] when other, extinct groups are considered, the relationship between birds and crocodiles appears distant.

9. Clade - Wikipedia

   en.wikipedia.org/wiki/Clade

   The science that tries to reconstruct phylogenetic trees and thus discover clades is called phylogenetics or cladistics, the latter term coined by Ernst Mayr (1965), derived from "clade". The results of phylogenetic/cladistic analyses are tree-shaped diagrams called cladograms; they, and all their branches, are phylogenetic hypotheses. [12]
