P\u00ebr ta kuptuar nj\u00eb her\u00eb e p\u00ebrgjithmon\u00eb, Briaud dhe koleg\u00ebt e tij mblodh\u00ebn t\u00eb dh\u00ebna nga misionet hap\u00ebsinore dhe eksperimentet h\u00ebnore me rreze lazer p\u00ebr t\u00eb p\u00ebrpiluar nj\u00eb profil t\u00eb karakteristikave t\u00eb ndryshme h\u00ebnore.<\/p>\n\n\n\n

Rezultatet e tyre, thon\u00eb Briaud dhe ekipi i tij, jan\u00eb konfirmim i atyre gjetjeve t\u00eb m\u00ebparshme. Dhe kjo ka disa implikime interesante p\u00ebr evolucionin e H\u00ebn\u00ebs.<\/p>\n\n\n\n
