Patent ID: 7254489

Claim:
One or more computer-readable media comprising computer executable instructions that, when executed, direct a computing system to perform a method comprising: reconstructing a predicted phylogenetic tree topology by: determining samples of characters of a plurality of known nodes; identifying each of the samples including a number of characters; calculating the number of characters being approximately equal to a factor of a natural logarithm of the number of the plurality of known nodes, selecting one or more of the plurality of known nodes that are within a predetermined threshold; yielding a reconstructed phylogenetic tree topology having one or more reconstructed nodes based on the selecting one or more of the plurality of known nodes; estimating a sequence of characters of each of the one or more nodes in the reconstructed phylogenetic tree topology in accordance with a stochastic mutation model using a majority function; presenting the reconstructed predicted phylogenetic tree topology; and determining closeness of relationship between species or individuals, based on the reconstructed phylogenetic tree topology.
