Evolution of immunoglobulin allotypes and phylogeny of apes.
Serum samples from 72 Pan troglodytes, 5 Pan paniscus, 22 Gorilla gorilla, 23 Pongo pygmaeus abelii, 5 Pongo pygmaeus pygmaeus, 2 hybrids P.p. abelii X P.p. pygmaeus and 13 Hylobates lar were tested for Gm(1, 2, 3, 5, 6, 10, 11, 13, 14, 15, 16, 17, 21, 24, 28), Km(1) and Bm(1, 2, 3, 4, 5, 6, 7, 8) immunoglobulin allotypes by the classical hemagglutination inhibition method. The distribution of the various alleles and phenotypes makes it possible to distinguish each species or subspecies. Common chimpanzees have the richest polymorphism. Pygmy chimpanzees share common phenotypes with gorillas. Bornean and Sumatran orangutans have their own patterns of polymorphism, as do gibbons. Our principal component plot and dendrogram are compatible with the traditional classification of Hominoidea [e.g. Simpson, Bull. Am. Mus. nat. Hist. 85: 1-350, 1945] in 3 families: Hominidae, Pongidae and Hylobatidae.
