Pakar genetika asal Itali Luigi Luca Cavalli-Sforza telah membuktikan bahwa mengelompokkan manusia dalam jenis-jenis "ras" adalah suatu usaha yang sia-sia. Dengan demikian, dari segi biologi, istilah seperti "ras Kaukasoid" dan pada umumnya, "ras manusia", tidak dianggap lagi. Fenotipe seseorang hanya ditentukan oleh sejumlah kecil gen. Secara biologis, hanya ada satu ras manusia modern, yaitu Homo sapiens.
