Tre ossa appartenenti a un braccio umano risalenti a circa 200'000 anni fa e attribuite alla linea evolutiva dell'Uomo di Neanderthal, sono state ritrovate dai ricercatori francesi del Centro nazionale della ricerca scientifica e dell'Istituto nazionale di archeologia sul sito preistorico di Tourville-la-Rivière (Alta Normandia), nel nord del paese.
La scoperta di questi fossili umani, tre ossa lunghe del braccio sinistro di un solo individuo, adulto o adolescente (omero, radio e cubito), spiega uno dei ricercatori, Bruno Maureille, “è eccezionale”, e molto rara nell'Europa del nord-ovest. L'uomo di Tourville-la-Rivière, come è stato soprannominato dai ricercatori, ha vissuto tra 236’000 e 183’000 anni fa (Paleolitico medio), e si tratterebbe quindi di un uomo pre-Neanderthal.
“Le caratteristiche morfologiche - ha osservato Maureille - annunciano i tratti che ritroveremo nell'uomo di Neanderthal e permettono di fare l'ipotesi che sia di un membro di questa linea evolutiva”.
