Bu topluluklara ait iki insan di\u015fi \u00fczerinde biyomolek\u00fcler analiz yapan ara\u015ft\u0131rmac\u0131lar, iskelet kal\u0131nt\u0131lar\u0131ndan birinin yakla\u015f\u0131k 25 bin ila 16 bin y\u0131l di\u011ferinin ise 7 bin 600 ila 6 bin 300 y\u0131l \u00f6ncesine ait oldu\u011funu belirledi.<\/p>\n
Her iki di\u015f \u00f6rne\u011finde derin ve yuvarlak oluklar tespit eden ara\u015ft\u0131rmac\u0131lar, bu a\u015f\u0131nmalar\u0131n areka cevizinin a\u011f\u0131zda emilmesi sonucu olu\u015ftu\u011funu saptad\u0131.<\/p>\n

Bu yemi\u015fin, Bat\u0131 toplumlar\u0131nda yeteri kadar bilinmedi\u011fini ifade eden Brumm, areka cevizinin d\u00fcnyada alkol, kafein ve nikotinden sonra en yayg\u0131n kullan\u0131lan d\u00f6rd\u00fcnc\u00fc “psikoaktif madde” oldu\u011funu kaydetti.<\/p>\n
