Here is a phylogenetic tree of 5 species of pines. At the tips of the tree are data for a character known as number of stomatal rows. This character refers to the number of rows of stomata on the underside of a needle. All species have either 1 or 2 rows. Using the Fitch algorithm, what is the minimum number of changes that have occurred on this phylogeny between 1 and 2 rows of stomata
