"Haemoproteus rouxi" Novy and MacNeal 1904 is a "nomen nudum". Haemoproteus Haemoproteus is a genus of alveolates that are parasitic in birds, reptiles and amphibians. Its name is derived from Greek: "Haima", "blood", and "Proteus", a sea god who had the power of assuming different shapes. The name "Haemoproteus" was first
Genomic evolution of birds several modifications and deletions which occurred in the exons of the genes implicated in the formation of enamel and dentine. It is thought that the common ancestor of birds already lacked mineralized teeth, and that later genome changes pushed the situation to the current status. Also, birds have the best vision system known in vertebrates. They have a higher number of photoreceptors, and most birds are tetrachromats. The only exception are penguins, which have only three functional opsin genes (and hence are trichromats). This exception could be related to the aquatic lifestyle, since marine mammals have also lost either one
