Phylogenetic analyses

Phylogenetic analyses. Kirsi Kostamo. The aim:. To construct a visual representation (a tree) to describe the assumed evolution occurring between and among different groups (individuals, populations, species, etc.) and to study the reliability of the consensus tree. Assumptions.

Bootstrapping

Bootstrapping. Method for assessing confidence in nodes of a tree Create a new data set by resampling characters randomly with replacement New data set is the same size as the original Variation found from this method is similar to what would be found by collecting new data sets

Consensus Trees

Consensus Trees. Loni Beaty. Review. Phylogenetic Trees -> Figure depicting evolutionary descent, communicating the evolutionary relationship among entities Important to know: Phylogenetic trees may not represent the true evolutionary history. Why is this?. Problems with Phylogenies.

Consensus Trees

Consensus Trees . Consensus trees. In MP or ML analyses, more than one best cladogram may be obtained. Consensus methods are a convenient means of summarizing these cladograms. Consensus trees are derivative whereas most parsimonious/likelihood trees are fundamental.
