Maximum likelihood methods have been developed in order to construct the most probable phylogenetic tree. The earliest methods of calculating the maximum likelihood used gene frequency data‚ and more recent approaches involve algorithms of amino acid and nucleotide sequences. The general equation for the likelihood L of a phylogenetic tree is defined as the probability of observing the data in a given tree under a specific substitution pattern‚ L=(data│tree). The tree with the highest L value is
