Did you know?
Maximum parsimony is an intuitive and simple criterion, and it is popular for this reason. However, although it is easy to score a phylogenetic tree (by counting the number of character-state changes), there is no algorithm to quickly generate the most-parsimonious tree. Meer weergeven In phylogenetics, maximum parsimony is an optimality criterion under which the phylogenetic tree that minimizes the total number of character-state changes (or minimizes the cost of differentially weighted … Meer weergeven In phylogenetics, parsimony is mostly interpreted as favoring the trees that minimize the amount of evolutionary change required (see for example ). Alternatively, … Meer weergeven The input data used in a maximum parsimony analysis is in the form of "characters" for a range of taxa. There is no generally … Meer weergeven A maximum parsimony analysis runs in a very straightforward fashion. Trees are scored according to the degree to which they imply a … Meer weergeven Parsimony is part of a class of character-based tree estimation methods which use a matrix of discrete phylogenetic characters and character states to infer one or more optimal phylogenetic trees for a set of taxa, commonly a set of species or reproductively isolated Meer weergeven The time required for a parsimony analysis (or any phylogenetic analysis) is proportional to the number of taxa (and characters) … Meer weergeven Maximum parsimony is an epistemologically straightforward approach that makes few mechanistic assumptions, and is popular for this reason.
