Document Summary
Selects as best the tree that is most probable given both the observed data and some prior assumptions about possible trees. To root this tree we pick another population that branched off earlier in evolutionary history from the entire clade that we are considering. Korean magpie lineage and the eurasian magpie lineage. A subpopulation from the eurasian lineage then traveled to the new world, and subsequently speciated to produce the black-billed and yellow-billed species now found in. 5. 4 distance methods: what are the types of data used to determine distances for constructing phylogenetic trees. We look to see how often the feature we are interested in occurs among them. But the chi-square test assumes that each sample evolved independently from one another. Another words, the test does not account for any shared evolutionary history among these species: now we can infer the evolutionary changes that gave rise to the characters that we observe.
