According to the author, Ronald Takaki, what originally separated the racial

groups?

What originally separated racial groups were the similar physical characteristics between members.

Explanation:

Takaki claims that originally racial groups were separated and established by the physical characteristics they had in common with each other. Thus, individuals who had the same skin color, the same eye shape and other similar physical characteristics, were grouped into a single racial group. Currently this type of separation is no longer possible, because the physical characteristics between people are no longer as defined and specific, since the interaction between races, promoted individuals who have characteristics of all of them.
