 But while Bernier initiated the use of the term “race” to distinguish different groups of humans based on physical traits, his failure to reflect on the relationship between racial division and the human race in general mitigated the scientific rigor of his definition (Bernasconi and Lott 2000, viii). Central to a scientific concept of race would be a resolution of the question of monogenesis versus polygenesis. Monogenesis adhered to the Biblical creation story in asserting that all humans descended from a common ancestor, perhaps Adam of the Book of Genesis; polygenesis, on the other hand, asserted that different human races descended from different ancestral roots. Thus, the former position contended that all races are nevertheless members of a common human species, whereas the latter saw races as distinct species.
