The Evolutionary Relationship between Microbial Rhodopsins and Metazoan Rhodopsins
Figure 2
(a) Fitch-Margoliash tree for all rhodopsin genes in human. (b) Fitch- Margoliash tree for all rhodopsin genes in chicken. Hydra rhodopsin gene serves as outgroup. The numbers adjacent to tree nodes are bootstrap values. The tree node where ancestral state is built on is marked with a filled black square .
