1 3023What is the main idea of maximum parsimony in phylogenetic tree construction? What are the drawbacks?
2 4983Bootstrap analysis evaluates evolutionary trees by sampling columns from the original alignment with replacement (multiplying or removing some of them) and computing a proportion of times that a particular branch appears in the resulting trees. What is the main idea behind this approach?
