This paper examines the controversy surrounding anthropologist Carleton S.
Coon's 1962 book, The Origin of Races. Coon maintained that the human sspec
ies was divided into five races before it had evolved into Homo sapiens and
that the races evolved into sapiens at different times. Coon's thesis was
used by segregationists in the United States as proof that African American
s were ``junior'' to white Americans and hence unfit for full participation
in American society. The paper examines the interactions among Coon, segre
gationist Carleton Putnam, geneticist Theodosius Dobzhansky, and anthropolo
gist Sherwood Washburn. The paper concludes that Coon actively aided the se
gregationist cause in violation of his own standards for scientific objecti
vity.
