Selon de pr\u00e9c\u00e9dentes datations par radiocarbone, les sp\u00e9cimens de la grotte de Spy en Belgique, o\u00f9 de nombreux restes humains ont \u00e9t\u00e9 retrouv\u00e9s depuis le 19\u00e8me si\u00e8cle, remontaient \u00e0 seulement 24 000 ans. Mais selon une \u00e9tude publi\u00e9e lundi dans la revue scientifique Pnas<\/em>, ils sont en fait vieux d’entre 44 200 et 40 600 ann\u00e9es.\u00a0L’\u00e9tude conclut ainsi que les N\u00e9andertaliens \u00abont disparu du nord de l’Europe (…) bien plus t\u00f4t que sugg\u00e9r\u00e9 auparavant\u00bb.<\/p>\n

Une \u00e9quipe multidisciplinaire de Belgique, de Grande-Bretagne et d’Allemagne a d\u00e9velopp\u00e9 une m\u00e9thode pour pr\u00e9parer les \u00e9chantillons, permettant d’\u00e9viter toute contamination ext\u00e9rieure, a expliqu\u00e9 \u00e0 l’Agence France-Presse (AFP) l’un des co-auteurs de l’\u00e9tude, Thibaut Deviese, de l’Universit\u00e9 d’Oxford et Aix-Marseille.<\/p>\n

\u00abPr\u00e8s de deux si\u00e8cles apr\u00e8s la d\u00e9couverte de l’enfant n\u00e9andertalien d’Engis, nous avons \u00e9t\u00e9 capables de lui donner un \u00e2ge fiable\u00bb, a d\u00e9clar\u00e9 Thibaut Deviese.\u00a0\u00abDater tous ces sp\u00e9cimens de Belgique \u00e9tait tr\u00e8s enthousiasmant, car ils ont jou\u00e9 un r\u00f4le majeur dans la compr\u00e9hension et la d\u00e9finition de l’Homme de N\u00e9andertal.\u00bb<\/p>\n

Des preuves existent qu’il a pu survivre plus longtemps dans d’autres r\u00e9gions qu’en Belgique, note toutefois l’\u00e9tude.\u00a0\u00abLa datation est cruciale en arch\u00e9ologie, car sans un cadre fiable de la chronologie, on ne peut \u00eatre s\u00fbrs de comprendre les relations entre le N\u00e9andertalien et l’Homo sapiens\u00bb, a-t-il soulign\u00e9.<\/p>\n<\/div>\n
