| Research Abstract |
The availability of large genomic sequence datasets allows us to perform the maximum likelihood analysis of the eutherian phylogenetic relationship. We demonstrate that the better model which takes into account the different tempos and modes of evolution among genes, should be used for phylogenetic inference in cases of large variation in evolutionary features among different genes, such as for genome-scale data.
