Parsimony: Why You Should Prefer Simpler Explanations

WebWhen a parsimony analysis results in more than a single most-parsimonious tree (MPT), it is shown that the number of homologous characters may vary significantly. We propose a … WebUse the principle of parsimony and molecular genetic data to choose a phylogenetic tree for your hypothesis of how the extant species were derived from the ancestor. Tree 2 requires the fewest mutations, making it the best choice. Can two different species that are members of the same clade have more than one common ancestor? nicole wallace twitter account
