L’Ethiopie \u00e9tait traditionnellement consid\u00e9r\u00e9e comme le berceau de l’homme moderne. Aujourd’hui, les arch\u00e9ologues ont trouv\u00e9 des fossiles plus anciens d’Homo sapiens au Maroc.<\/a><\/p>\n<\/div>\nLes scientifiques \u00e9taient d’avis que les g\u00e8nes de ces anciens hominid\u00e9s ont \u00e9t\u00e9 introduits par un processus d’introgression, un mouvement de g\u00e8nes entre deux populations qui se produit lorsque les membres d’une population s’accouplent avec ceux de l’autre, puis que les hybrides qui en r\u00e9sultent se reproduisent avec les membres des populations parentales.<\/p>\n
Selon les recherches, cette esp\u00e8ce a crois\u00e9 le chemin de l’Homo sapiens africain il y a 43.000 ans et a laiss\u00e9 son empreinte g\u00e9n\u00e9tique, mais comme il n’y a pas de traces de fossiles pour le prouver, les chercheurs les appellent l’esp\u00e8ce \u00ab\u00a0fant\u00f4me\u00a0\u00bb.<\/p>\n<\/div>\n
