Ancestral Sequences | Infer Ancestral Sequences (ML)
This option uses the Maximum Likelihood method to estimate the ancestral state of each node in a phylogenetic tree. The state is chosen to be the one that maximizes the probability of the given sequence data under the selected model of nucleotide or amino acid evolution. Inferring ancestral sequences using ML, on average, gives more accurate results than using Maximum Parsimony, especially when the phylogenetic tree includes long branches.
