Solution
The advantage of using a statistical approach, such as maximum likelihood, when constructing a cladogram, rather than relying on parsimony alone, is that different rates of evolution can be used for different characters. This allows for a more nuanced and accurate representation of evolutionary relationships. While parsimony is a useful tool, it operates under the assumption that the simplest explanation (i.e., the one involving the fewest evolutionary changes) is the most likely. However, this is not always the case in nature, where evolution can often be complex and non-linear. By using a statistical approach, we can account for these complexities and provide a more accurate picture of evolutionary history.
