Use the cladistic approach (using parsimony) to draw the tree that derives from the same data matrix above. Map both the species and the traits to your tree.
The cladistic approach is a method of analyzing the evolutionary relationships among a group of organisms based on shared, derived characteristics, or synapomorphies. This approach assumes that the members of a group share a common ancestor and that the relationships among those members can be reconstructed by identifying shared characteristics and inferring the sequence of branching events that led to their diversification. The cladistic approach emphasizes the use of parsimony, or the principle of choosing the simplest explanation that is consistent with the data, to construct hypotheses of evolutionary relationships.
