Problem
Which statement below is true of parsimonious trees?
A
The most parsimonious tree requires the fewest evolutionary events to have occurred in the form of shared ancestral characters.
B
Given the rules of how morphological traits change over time, a tree can be found that reflects the most likely sequence of evolutionary events.
C
Given the rules of how DNA changes over time, a tree can be found that reflects the most likely sequence of evolutionary events.
D
Trees can be constructed that are the most parsimonious or the most likely, but not both at the same time.
E
The most parsimonious tree requires the fewest evolutionary events to have occurred in the form of shared derived characters.
