To apply parsimony to constructing a phylogenetic tree, To apply parsimony to constructing a phylogenetic tree, choose the tree that assumes all evolutionary changes are equally probable. choose the tree that represents the fewest evolutionary changes in either DNA sequences or morphology. choose the tree in which the branch points are based on as many shared derived characters as possible. base phylogenetic trees only on the fossil record, as this provides the simplest explanation for evolution. choose the tree with the fewest branch points.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
