Phylogenetics - Wikipedia
WEBIn biology, phylogenetics ( / ˌfaɪloʊdʒəˈnɛtɪks, - lə -/) [1] [2] [3] is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by phylogenetic inference, methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or ...
Phylogenetic tree - Wikipedia
WEBA 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 ...
Phylogenesis - Wikipedia
WEBThe result of these analyses is a phylogeny (also known as a phylogenetic tree) – a diagrammatic hypothesis about the history of the evolutionary relationships of a group of organisms. Phylogenetic analyses have become central to understanding biodiversity, evolution, ecological genetics and genomes .
Evolution - Wikipedia
WEBEvolution by natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population. It embodies three principles: Variation exists within populations of organisms with respect to morphology, physiology and behaviour (phenotypic variation).
Tree of life (biology) - Wikipedia
WEBIn contemporary usage, tree of life refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth. Two public databases for the tree of life are TimeTree, for phylogeny and divergence times, and the Open Tree of Life, for phylogeny.
Molecular phylogenetics - Wikipedia
WEBMolecular phylogenetics (/ m ə ˈ l ɛ k j ʊ l ər ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s, m ɒ-, m oʊ-/) is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the ...
Phylogeny - Simple English Wikipedia, the free encyclopedia
WEBA phylogeny is a proposal of how organisms are related by their evolutionary history. p336 It is based on the evidence that all living things are related by common descent. The evidence for phylogeny comes from palaeontology, comparative anatomy, and DNA sequence analysis. The main product of phylogenetics is a phylogenetic tree or tree of life ...

WEBMar 22, 2024 · Phylogeny, the history of the evolution of a species or group, especially in reference to lines of descent and relationships among broad groups of organisms. Fundamental to phylogeny is the proposition, universally accepted in the scientific community, that plants or animals of different species.
