Phylogeny and Molecular Evolution Simulation

Question 1 of 4

Which statement is true of the parsimony method for reconstructing phylogeny?

The preferred phylogenetic tree under the parsimony method is the tree with the fewest branches.

The preferred phylogenetic tree under the parsimony method is the tree that requires the smallest number of evolutionary changes to explain the data.

Parsimony assumes that evolutionary convergences do not occur between biological lineages.

Parsimony assumes that once a character changes, it never reverses to the previous state.
