Many methods have been developed for finding the commonalities between URLanisms to study their phylogeny. The structure of metabolic networks also reveal important insights into metabolic capacity of species as well as into the habitats where they have evolved. Horizontal gene transfer brings two species, which have evolved in similar environmental condition or lifestyle, close to each other in phylogenetic study based on metabolic network topology. We construct metabolic networks of 79 fully URLanisms and compare their architectures. We use spectral density of normalized Laplacian matrix for comparing structure of networks. The eigenvalues of this matrix not only reflects the global architecture of a network , but also the local topologies which are produced by different graph evolutionary processes like motif duplication or joining. A divergence measure on spectral densities is used to quantify the distances between different metabolic networks and a split tree is constructed from these distances to analyze the phylogeny  . In our analysis  we show more interest on the species, who belong to different classes  but come in the vicinity of each other in phylogeny  . With this focus, we reveal interesting insights into the phylogenetic commonality between URLanisms.

The structure of metabolic networks also reveals valuable insights into metabolic capacity of species as well as into the habitats where they have evolved. We construct metabolic networks of 79 fully URLanisms and compare their architectures. We use spectral density of normalized Laplacian matrix for comparing structure of networks. The eigenvalues of this matrix reflect not only the global architecture of a network but also the local topologies that are produced by different graph evolutionary processes like motif duplication or joining. A divergence measure on spectral densities is used to quantify the distances between various metabolic networks, and a split network is constructed to analyze the phylogeny from these distances . In our analysis , we show more interest on the species, which belong to different classes , but come in the vicinity of each other in phylogeny . We try to explore if they have evolved in similar environmental condition or lifestyle . With this focus, we reveal interesting insights into the phylogenetic commonality between URLanisms.
