The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. [3] [4] [5] Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process ...
Molecular systematics uses DNA sequence data for tracking evolutionary changes, thus paraphyly and sometimes phylogenetic polyphyly signal ancestor-descendant transformations at the taxon level, but otherwise molecular phylogenetics makes no provision for extinct paraphyly. Additional transformational analysis is needed to infer serial descent.
The multispecies coalescent has profound implications for the theory and practice of molecular phylogenetics. [3] [4] Since individual gene trees can differ from the species tree one cannot estimate the tree for a single locus and assume that the gene tree correspond the species tree. In fact, one can be virtually certain that any individual ...
That molecular phylogenetics could compete with comparative anthropology for determining the proximity of species to humans. Wilson and King realized in 1975, that while there was equity between the level of molecular evolution branching from chimp to human to putative LCA, that there was an inequity in morphological evolution. Comparative ...
Computational phylogenetics can be used to investigate a language as an evolutionary system. The evolution of human language closely corresponds with human's biological evolution which allows phylogenetic methods to be applied. The concept of a "tree" serves as an efficient way to represent relationships between languages and language splits.
In the late 20th-century, DNA sequencing led to molecular phylogenetics and the reorganization of the tree of life into the three-domain system by Carl Woese. In addition, the newly recognized factors of symbiogenesis and horizontal gene transfer introduced yet more complexity into evolutionary theory.
Phylogenomics is the intersection of the fields of evolution and genomics. [1] The term has been used in multiple ways to refer to analysis that involves genome data and evolutionary reconstructions. [2] It is a group of techniques within the larger fields of phylogenetics and genomics.
