Excerpt
In these days, when anything pertaining to evolution and the species relationships of man has news interest, much attention will probably be paid to a series of articles by Landsteiner and Miller1 of the Rockefeller Institute on the serologic relationships of the blood of the primates. This topic aroused interest in the early days of immunologic investigation, when the blood relationships of different species, as shown by the new methods, were found to throw much light on the problems of biologic relationship and evolution. Nuttail's famous monograph on blood immunity and blood relationship, published in 1904, brought out the fact that precipitin tests with blood serum from primates showed a close relationship between man and the orang-utan, chimpanzee and gorilla, but less relationship between man and the monkeys. Other investigators obtained similar results and indicated that it was difficult to distinguish between human serum and that of the anthropoids
