"Data for native populations collected by R. Biasutti prior to 1940"

Use with caution; The best known of these maps is that composed by the Italian geographer Renato Biasutti, which was based on von Luschan's chromatic scale. This map has gained broad circulation in several widely distributed publications (Barsh 2003, Lewontin 1995, Roberts 1977, Walter 1971), despite the fact that, for areas with no data, Biasutti simply filled in the map by extrapolation from findings obtained in other areas.

The 'white' streak across Morocco and Algeria was not present in the original map by Biasutti, but it appeared on later maps and has probably no basis in reality. Biasutti's own map shows an intermediate skin tone value in this band. The map's intended use is in articles dealing with the history of the notion of race, and it should not be used as an up-to-date reference.
