Solution
The advantage of using a statistical approach like 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 is because maximum likelihood methods can incorporate models of evolution that account for varying rates of change across different lineages and characters, providing a more nuanced and potentially accurate view of evolutionary history. On the other hand, parsimony methods assume that the simplest explanation (i.e., the one involving the fewest changes) is the most likely, which may not always be the case.
