Caucasoids or more correctly Caucasians refers to a major race that are native to a geographical area that includes Europe, and small parts of North Africa and West Asia. This area corresponds to major geographic barriers that made contacts and genetic exchange between different groups difficult: Oceans, the Himalayas and Urals mountain ranges, and deserts.
The terms derive from the Caucasus Mountains between the Black Sea and the Caspian Sea. The term Caucasians was introduced in 1795 by the German anthropologist Johann Friedrich Blumenbach he having concluded that Europeans' ancestral origins lay in this region.
