Below are six faces. Each face represents a species. Seven characters are listed in the table, along with an
ancestral and a derived character state for each character. Please identify the derived characters and
complete a character matrix for these species that includes only the derived characters. Species 6 is the
outgroup in this problem, so assume that it possesses only ancestral characters.

Expert Solution

Step 1

Introduction :

Maximum parsimony is an optimality criterion in phylogenetics that favours the phylogenetic tree with the fewest character-state changes overall. The ideal tree will reduce homoplasy in accordance with the maximum-parsimony criterion. In other words, the shortest tree that adequately describes the data is preferred under this criterion.
