WebTerms in this set (69) What are phylogenies? The evolutionary history of a species or group of unrelated species. How are phylogenies constructed? They are constructed as a … WebPhylogenetic trees composed with a nontrivial number of input sequences are constructed using computational phylogenetics methods. Distance-matrix methods such as neighbor-joining or UPGMA , which calculate genetic distance from multiple sequence alignments , are simplest to implement, but do not invoke an evolutionary model.

WebConceptual and statistical advances over the last 15 years have demonstrated several ways in which comparisons can be enhanced by consideration of phylogenetic information, i.e., empirical estimates of the ways in which organisms are related (evolutionary trees). Choice of species to be compared should be informed by phylogenetic information. WebA phylogeny, also known as a tree, is an explanation of how sequences evolved, their genealogical relationships, and therefore how they came to be the way they are today.
