In particular, the interferon families fall into distinct clades, with the exception of the platypus IFNA genes, which appear ancestral to the IFNA, IFNW, and IFND genes of the other species. Within each of the families, the genes fall into clades according to species, with no interdigitation of genes from different species in any clade (Figure 3). Additionally, the bat genes from one bat species are typically, but not universally, more closely related to the orthologous genes from the other bat species than to those of pigs or humans. The bat genes are typically but not universally more closely related to the orthologous pig genes than to the orthologous human genes."}
