Moreover, the concept of race is outdated and deprecated in the scientific community, mainly because most people (and nations) had some influence of several of them and can’t be strictly categorized as one or the other.

There are even large groups of black jews living in Ethiopia, Uganda, Nigeria and other countries, which is a revelation for many.
