Les plus anciens fossiles class\u00e9s dans le genre Homo sont connus \u00e0 partir d\u2019environ 2,7\u00a0millions d\u2019ann\u00e9es. Mais ils sont tr\u00e8s rares et tr\u00e8s incomplets. Bien s\u00fbr, avec si peu de fossiles, on a beaucoup de mal \u00e0 bien comprendre les choses. L\u2019anc\u00eatre du genre Homo est forc\u00e9ment \u00e0 chercher parmi les australopith\u00e8ques qui vivaient avant eux. Mais il y a plusieurs esp\u00e8ces d\u2019australopith\u00e8ques, et avec si peu de fossiles des premiers Homo, on n\u2019arrive pas pour l\u2019instant \u00e0 savoir de quelle esp\u00e8ce d\u2019australopith\u00e8que ils descendent. Mais on sait qu\u2019en Afrique de l\u2019est, le climat change entre 3 et 2\u00a0millions d\u2019ann\u00e9es et que les environnements se transforment, devenant des savanes. Tous les animaux \u00e9voluent pour s\u2019adapter \u00e0 ce nouvel environnement, ou disparaissent s\u2019ils ne parviennent pas \u00e0 s\u2019y adapter. Nos anc\u00eatres sont des animaux comme les autres, et c\u2019est en \u00e9voluant en lien avec les changements de l\u2019environnement que certains australopith\u00e8ques ont \u00e9volu\u00e9 pour donner les premiers repr\u00e9sentants du genre Homo.\u00a0\u00bb<\/p>\n<p><b>Fran\u00e7ois MARCHAL.
