The comparative genomics between different rhodopsin-like family groups (α, β, γ and δ) is
not well studied. We used a combination of phylogenetic analysis and statistical genomic
methods to compare rhodopsin-like family proteins in species likely symbolic of this family's
evolutionary progression. For intra-cluster relationships, we applied mathematical
optimisation to enhance the tree search produced by the neighbour joining method (NJ) and
compared it with maximum likelihood (ML) method. To infer inter-clusters relationships, we …
