Describe maximum parsimony Flashcards

1
Q

What is the principle of maximum parsimony?

A

The principle of maximum parsimony states that the simplest explanation or path, requiring the fewest evolutionary changes, is preferred when constructing phylogenetic trees.

Q

In maximum parsimony, how is a tree evaluated?

A

A tree is evaluated based on the total number of character changes it requires, with fewer changes being preferred.
