While the precipitin tests do not differentiate, according to the results of previous workers, between the serum proteins of man and chimpanzee, a clear-cut differentiation between the blood cells of man and the anthropoids was obtained by means of hemagglutinins. According to our tests on bloods of whites and negroes, constant racial serological differences among human bloods, if they exist at all, are certainly smaller than the differences between the bloods of man and the anthropoid apes. The serological differences between man and the lower monkeys appear to be no greater than those between the anthropoid apes and the lower monkeys. These findings confirm the opinion that the anthropoid apes do not rank in the genealogical tree between lower monkeys and man.
虽然沉淀素试验不能像以前的工作者所表明的那样区分人和黑猩猩的血清蛋白质,但通过血凝素可以清楚地区分人和类人猿的血细胞。根据我们对白人和黑人血液的测试,如果人类血液之间存在恒定的种族血清学差异,那么它们肯定比人和类人猿血液之间的差异小。人类和低级灵长类动物之间的血清学差异似乎不比类人猿和低级灵长类动物之间的差异大。这些发现证实了这样一种观点,即类人猿在进化树上并不介于低级猴子和人类之间。
