Pour savoir qui est le premier, il faut regarder tr\u00e8s tr\u00e8s loin dans le pass\u00e9 parmi les fossiles de nos anc\u00eatres. Tous les humains actuels appartiennent \u00e0 l\u2019esp\u00e8ce Homo sapiens et dans le pass\u00e9, il y a eu de nombreuses autres esp\u00e8ces faisant partie du genre Homo. Si pour simplifier on consid\u00e8re qu\u2019un humain est un repr\u00e9sentant du genre Homo, alors les plus anciens fossiles attribu\u00e9s par les chercheurs au genre Homo sont dat\u00e9s d\u2019environ 2,7\u00a0millions d\u2019ann\u00e9es. Il s\u2019agit probablement d\u2019une esp\u00e8ce appel\u00e9e Homo habilis, m\u00eame si les fossiles sont tellement rares et incomplets que les chercheurs ont juste dit qu\u2019il s\u2019agissait de repr\u00e9sentants du genre Homo, sans se prononcer sur l\u2019esp\u00e8ce. Si on remonte encore plus loin dans le pass\u00e9, on ne voit plus parmi les fossiles que les australopith\u00e8ques, comme Lucy par exemple, qui elle est dat\u00e9e d\u2019environ 3,2\u00a0millions d\u2019ann\u00e9es. Mais les australopith\u00e8ques \u00e9taient-ils des \u00eatres humains\u00a0?
