Idea of plural origins
of the species
held in the early nineteenth century. One group
, exemplified by S. G. Morton, rationalized a form
of scientific racism
, while a second group
, of which J. C.
Nott and G. R. Gliddon were representative, approached the problem
using both anthropological theory
and socioeconomic ideas. Both groups
, however, were strict supporters of polygenism.
