the bulk of the brazilian population descends from three main source populations (either alone, or more commonly, in varying combinations mixed in varying degrees); early european settlers (chiefly ethnic portuguese, but also portuguese new christians of ethnic sephardic jewish origin forced to convert to christianity), sub-saharan africans (yoruba, ewe, akan, bantu, and others), and the indigenous peoples in brazil (mostly tupi and guarani, but also other many indigenous brazilian ethnic groups).
