Which tree is most parsimonious?
Then, what is a parsimonious tree?
The parsimony principle is basic to all science and tells us to choose the simplest scientific explanation that fits the evidence. In terms of tree-building, that means that, all other things being equal, the best hypothesis is the one that requires the fewest evolutionary changes.
Furthermore, which of the four possible phylogenetic trees is the most parsimonious? From this information, they have constructed four possible phylogenetic trees. Tree III requires the fewest base-change events, so it is the most parsimonious phylogenetic tree.
Hereof, what is maximum parsimony method?
Maximum Parsimony is a character-based approach that infers a phylogenetic tree by minimizing the total number of evolutionary steps required to explain a given set of data assigned on the leaves.
How do you determine parsimony?
In general, parsimony is the principle that the simplest explanation that can explain the data is to be preferred. In the analysis of phylogeny, parsimony means that a hypothesis of relationships that requires the smallest number of character changes is most likely to be correct.
